SYNOPSIS¶
feh |
[options] [files | directories | URLs ...] |
VERSION¶
This manual documentsfeh
3.1.3
Compile-time switches: libcurl support enabled, natural sorting support enabled, Xinerama support enabled, builtin EXIF support enabled
DESCRIPTION¶
feh
is a light-weight, configurable and versatile image
viewer. It is aimed at command line users, but can also be started from
graphical file managers. Apart from viewing images, it can compile text and
thumbnail listings, show (un)loadable files, set X11 backgrounds, and more.
Features include filelists, various image sorting modes, custom
action scripts, and image captions. feh
can be
controlled by configurable keyboard and mouse shortcuts, terminal input and
signals. When no file arguments or filelists are specified and
--start-at
is not used, feh
displays all files in the current directory.
EXIF tags are supported either using exiv2 / exifgrep via
--info
(see the
USAGE EXAMPLES
section), or as a builtin feature by compiling
feh
with exif=1. In this build of
feh
, builtin EXIF support is enabled.
MODES¶
feh
is based on various modes, which are selected at
startup by command line options.
Slideshow mode is the default. It opens a window and displays the first image in it; the slideshow position can be advanced (or otherwise changed) using keyboard and mouse shortcuts. In slideshow mode, images can be deleted either from the filelist or from the disk, a changed filelist can also be saved to the disk and reopened at a later time. An image can also be read from stdin via “feh -”.
Montage mode forms a montage from the filelist. The resulting image can be viewed or saved, and its size can be limited by height, width or both.
Index mode forms an index print from the filelist. Image thumbnails are shown along with the filename, size and dimensions, printed using a truetype font of your choice. The resulting image can be viewed or saved, and its size can be limited by height, width or both.
Thumbnail mode is like index mode, but the mini-images are clickable and open the selected image in a new window.
Multiwindow mode shows images in multiple windows, instead of as a slideshow in one window. Don't use with a large filelist ;)
List mode doesn't display images. Instead, it outputs an
ls
-style listing of the
files in the filelist, including image info such as size, number of pixels,
type, etc. There is also a Customlist mode which prints image info in a
custom format specified by a printf-like format string.
feh
can also list either all the loadable
files in a filelist or all the unloadable files. This is useful for preening
a directory.
SUPPORTED FORMATS¶
feh
can open any format supported by imlib2, most
notably jpeg, png, pnm, tiff, and bmp. The gif format is also supported, but
only for static images. In case of animations, only the first frame will be
shown. If the convert binary (supplied by ImageMagick) is available, it also
has limited support for many other file types, such as svg, xcf and otf. If
dcraw is available, feh
also supports RAW files
provided by cameras and will display the embedded thumbnails. Use
--conversion-timeout
timeout
with a non-negative value to enable support for these formats.
OPTIONS¶
-A
,--action
[flag][[title]]action- Specify a shell command as an action to perform on the image. In slideshow
or multiwindow mode, the action will be run when the action_0 key is
pressed, in list mode, it will be run for each file. In
loadable/unloadable mode, it will be run for each loadable/unloadable
file, respectively. In thumbnail mode, clicking on an image will cause the
action to run instead of opening the image.
If flag is “;”,
feh
will reload the current image instead of switching to the next one (slideshow mode) or closing the window (multiwindow mode) after executing the action. If [title] is specified (note the literal “[” and “]”),--draw-actions
will display title instead of action in the action list. Note that title must not start with a space. If it does, the action is handled as if it did not have a title. This special case exists for backwards compatibility reasons and makes sure that actions like “[ -L %F ] && foo” still work.The action will be executed by /bin/sh. Use format specifiers to refer to image info, see FORMAT SPECIFIERS for details. Example usage: “feh -A “mv ~/images/%N” *”.
--action1
..--action9
[flag][[title]]action- Extra actions which can be set and triggered using the appropriate number key.
--auto-rotate
- (optional feature, enabled in this build) Automatically rotate images based on EXIF data. Does not alter the image files.
-Z
,--auto-zoom
- Zoom pictures to screen size in fullscreen / fixed geometry mode.
-x
,--borderless
- Create borderless windows.
--cache-size
size- Set imlib2 in-memory cache to size MiB. A higher cache size can significantly improve performance especially for small slide shows, however at the cost of increased memory consumption. size must be between 0 and 2048 MiB and defaults to 4.
-P
,--cache-thumbnails
- Enable thumbnail caching. Thumbnails are saved in $XDG_CACHE_HOME/thumbnails, which defaults to ~/.cache/thumbnails. Note that thumbnails are only cached if the configured thumbnail size does not exceed 256x256 pixels.
-K
,--caption-path
path- Path to directory containing image captions. This turns on caption viewing, and if captions are found in path, which is relative to the directory of each image, they are overlayed on the displayed image. E.g. with caption path “captions/”, and viewing image “images/foo.jpg”, the caption will be looked for in “images/captions/foo.jpg.txt”.
--conversion-timeout
timeoutfeh
can use ImageMagick to try converting unloadable files into a supported file format. As this can take a long time, it is disabled by default. Set timeout to a non-negative value to enable it. A positive value specifies after how many seconds conversion attempts should be aborted, zero causesfeh
to try indefinitely. Negative values restore the default by disabling conversion altogether.-L
,--customlist
format- Don't display images, print image info according to format instead. See FORMAT SPECIFIERS.
-G
,--draw-actions
- Draw the defined actions and what they do at the top-left of the image.
--draw-exif
- (optional feature, enabled in this build) display some EXIF information in
the bottom left corner, similar to using
--info
with exiv2 / exifgrep . -d
,--draw-filename
- Draw the file name at the top-left of the image.
--draw-tinted
- Show overlay texts (as created by
--draw-filename
et al) on a semi-transparent background to improve their readability --edit
- Enable basic editing of files. This makes rotation and mirroring (bound to “<”, “>”, “|”, and “_” by default) change the underlying file and not just its displayed content.
-f
,--filelist
file- This option is similar to the playlists used by music software. If
file exists, it will be read for a list of files to
load, in the order they appear. The format is a list of image file names,
absolute or relative to the current directory, one file name per line.
If file doesn't exist, it will be created from the internal filelist at the end of a viewing session. This is best used to store the results of complex sorts (
-Spixels
for example) for later viewing.Any changes to the internal filelist (such as deleting a file or it being pruned for being unloadable) will be saved to file when
feh
exits. You can add files to filelists by specifying them on the command line when also specifying the list.If file is “-”,
feh
will read the filelist from its standard input. -e
,--font
font- Set global font. Should be a truetype font, resident in the current directory or the font directory, and should be defined in the form fontname/points, like “myfont/12”.
-C
,--fontpath
path- Specify path as extra directory in which to search for fonts; can be used multiple times to add multiple paths.
--force-aliasing
- Disable anti-aliasing for zooming, background setting etc.
-I
,--fullindex
- Same as index mode, but with additional information below the thumbnails.
Works just like “feh --index --index-info
"%n\n%S\n%wx%h"”. Enables
MONTAGE MODE OPTIONS.
Note: This option needs to load all images to calculate the dimensions of the
feh
window, so when using it with many files it will take a while before afeh
window is visible. Use--preload
to get a progress bar. -F
,--fullscreen
- Make the window fullscreen. Note that in this mode, large images will
always be scaled down to fit the screen, and
--zoom
zoom only affects smaller images and never scales larger than necessary to fit the screen size. The only exception is a zoom of 100, in which case images will always be shown at 100% zoom.When combined with
--thumbnails
, this option only affects images opened from the thumbnail overview. The thumbnail list itself will still be windowed. -g
,--geometry
widthx
height |+
x+
y | widthx
height+
x+
y- Use a fixed window size as specified in the X-style geometry
string, e.g. 640x480. An optional +x+y window offset
can be specified. Combine with
--scale-down
to scale down larger images like in fullscreen mode. Note that this option does not enforce the window size; changing it by a tiling WM or manually is still possible. However, auto-resize remains disabled. -Y
,--hide-pointer
- Hide the pointer (useful for slideshows).
-B
,--image-bg
style- Use style as background for transparent image parts
and the like. Accepted values: default, checks, or an XColor (e.g.
“black” or “#428bdd”). In windowed mode, the
default is checks (a checkered background so transparent image parts are
easy to see). In fullscreen and background setting mode,
checks
is not accepted and the default is black. -i
,--index
- Enable Index mode. Index mode is similar to montage mode, and accepts the same options. It creates an index print of thumbnails, printing the image name beneath each thumbnail. Index mode enables certain other options, see INDEX AND THUMBNAIL MODE OPTIONS and MONTAGE MODE OPTIONS.
--info
[flag]command_line- Execute command_line and display its output in the bottom left corner of the image. Can be used to display e.g. image dimensions or EXIF information. Supports FORMAT SPECIFIERS. If flag is set to “;”, the output will not be displayed by default, but has to be enabled by the toggle_info key.
--insecure
- When viewing files with HTTPS, this option disables all certificate checks. It allows images on sites with self-signed or expired certificates to be opened, but is no more secure than plain HTTP.
-k
,--keep-http
- When viewing files using HTTP,
feh
normally deletes the local copies after viewing, or, if caching, on exit. This option permanently stores them on disk, either in the directory specified by--output-dir
, or in the current working directory. --keep-zoom-vp
- When switching images, keep zoom and viewport settings (zoom level and X, Y offsets)
-l
,--list
- Don't display images. Analyze them and display an ls(1) - style listing. Useful in scripts to hunt out images of a certain size/resolution/type etc.
-U
,--loadable
- Don't display images. Just print out their names if imlib2 can successfully load them. Returns false if at least one image failed to load.
--max-dimension
width x height- Only show images with width <= width and height <= height. If you only care about one parameter, set the other to 0 (or a negative value).
-M
,--menu-font
font- Use font (truetype, with size, like “yudit/12”) as menu font.
--min-dimension
width x height- Only show images with width >= width and height >= height. If you only care about one parameter, set the other to 0.
-m
,--montage
- Enable montage mode. Montage mode creates a new image consisting of a grid of thumbnails of the images in the filelist. When montage mode is selected, certain other options become available. See MONTAGE MODE OPTIONS.
-w
,--multiwindow
- Disable slideshow mode. With this setting, instead of opening multiple files in slideshow mode, multiple windows will be opened; one per file.
--no-jump-on-resort
- Don't jump to the first image after resorting the filelist.
-N
,--no-menus
- Don't load or show any menus.
--no-screen-clip
- By default, window sizes are limited to the screen size. With this option, windows will have the size of the image inside them. Note that they may become very large this way, making them unmanageable in certain window managers.
--no-xinerama
- (optional feature, enabled in this build) Disable Xinerama support.
--on-last-slide
hold
|quit
|resume
- Select behaviour when trying to select the next image on the last slide
(or the previous image on the first slide) in a slide show.
With
hold
,feh
will stop advancing images in this case and continue displaying the first/last image, respectively. This is intended for linear slide shows. Behaviour is unspecified when using other navigation commands than previous and next image.quit
will causefeh
to quit when trying to advance past the last image in the slide show.resume
is the default behaviour: On the last (first) image,feh
will wrap around to the first (last) image. -j
,--output-dir
directory- Save files to directory when using
--keep-http
or the save_image command. By default, files are saved in the current working directory. -p
,--preload
- Preload images. This doesn't mean hold them in RAM, it means run through them and eliminate unloadable images first. Otherwise they will be removed as you flick through. This also analyses the images to get data for use in sorting, such as pixel size, type etc. A preload run will be automatically performed if you specify one of these sort modes.
-q
,--quiet
- Don't report non-fatal errors for failed loads. Verbose and quiet modes are not mutually exclusive, the first controls informational messages, the second only errors.
-z
,--randomize
- When viewing multiple files in a slideshow, randomize the file list before displaying. The list is re-randomized whenever the slideshow cycles (that is, transitions from last to first image).
-r
,--recursive
- Recursively expand any directories in the command line arguments to the content of those directories, all the way down to the bottom level.
--no-recursive
- Don't recursively expand any directories. This is the default, but this
option is useful to override themes containing
--recursive
. -R
,--reload
int- Reload filelist and current image after int seconds.
Useful for viewing HTTP webcams or frequently changing directories. (Note
that filelist reloading is still experimental.)
If an image is removed,
feh
will either show the next one or quit. However, if an image still exists, but can no longer be loaded,feh
will continue to try loading it. -n
,--reverse
- Reverse the sort order. Use this to invert the order of the filelist. E.g.
to sort in reverse width order, use
-nSwidth
. -.
,--scale-down
- Scale images to fit window geometry (defaults to screen size when no
geometry was specified). Note that the window geometry is not updated when
changing images at the moment. This option is recommended for tiling
window managers. This option is ignored when in fullscreen and thumbnail
list mode.
In tiling environments, this also causes the image to be centered in the window.
--scroll-step
count- Scroll count pixels whenever scroll_up, scroll_down, scroll_left or scroll_right is pressed. Note that this option accepts negative numbers in case you need to reverse the scroll direction. See KEYS CONFIG SYNTAX for how to reverse it permanently. Default: 20
-D
,--slideshow-delay
float- For slideshow mode, wait float seconds between
automatically changing slides. Useful for presentations. Specify a
negative number to set the delay (which will then be
float * (-1)), but start
feh
in paused mode. -S
,--sort
sort_type- Sort file list according to image parameters. Allowed sort types are:
name
,filename
,dirname
,mtime
,width
,height
,pixels
,size
,format
. For sort modes other thanname
,filename
,dirname
, ormtime
, a preload run is necessary, causing a delay proportional to the number of images in the list.mtime
starts with the most recently modified image.width
,height
,pixels
andsize
start with the smallest. Use--reverse
to sort by oldest or largest first.For
name
,filename
, anddirname
you can use--version-sort
to sort numbers naturally, so that e.g. 10.jpg comes after 2.jpg. -|
,--start-at
filename- Start the filelist at filename. If no other files or
filelists were specified on the command line,
feh
will first load all files from the directory in which filename resides. This way, it's possible to look at a specific image and use the next / prev keys to browse through the directory. See USAGE EXAMPLES for examples.Note: If you use relative paths in your filelist, filename should also be a relative path. If you use absolute paths, it should also be an absolute path. If
feh
cannot find an exact match, it will compare basenames (filenames without the directory suffix). This may lead to mismatches if several files in your filelist have the same basename. -T
,--theme
theme- Load options from config file with name theme - see
THEMES CONFIG SYNTAX for
more info. Note that command line options always override theme options.
The theme can also be set via the program name (e.g. with symlinks), so by
default
feh
will look for a “feh
” theme. -t
,--thumbnails
- Same as Index mode, but the thumbnails are clickable image launchers. Note
that
--fullscreen
and--scale-down
do not affect the thumbnail window. They do, however, work for image windows launched from thumbnail mode. Also supports INDEX AND THUMBNAIL MODE OPTIONS as well as MONTAGE MODE OPTIONS. -~
,--thumb-title
string- Set title for windows opened from thumbnail mode. See also FORMAT SPECIFIERS.
-^
,--title
title- Set window title. Applies to all windows except those opened from thumbnail mode. See FORMAT SPECIFIERS.
-u
,--unloadable
- Don't display images. Just print out their names if imlib2 can NOT successfully load them. Returns false if at least one image was loadable.
-V
,--verbose
- output useful information, progress bars, etc.
-v
,--version
- output version information and exit.
--version-sort
- (optional feature, enabled in this build) When combined with
--sort name
,--sort filename
, or--sort dirname
: use natural sorting for file and directory names. In this mode, filenames are sorted as an ordinary human would expect, e.g. “2.jpg” comes before “10.jpg”. Note that this option only has an effect when a sort mode is set using--sort
. --xinerama-index
screen- (optional feature, enabled in this build) Override
feh
's idea of the active Xinerama screen. May be useful in certain circumstances where the window manager places the feh window on Xinerama screen A whilefeh
assumes that it will be placed on screen B.In background setting mode: When used with any option other than
--bg-tile
: Only set wallpaper on screen. All other screens will be filled black/white. This is most useful in a Xinerama configuration with overlapping screens. For instance, assume you have two overlapping displays (index 0 and 1), where index 0 is smaller. To center a background on the display with index 0 and fill the extra space on index 1 black/white, use “--xinerama-index 0” when setting the wallpaper. --zoom
percent |max
|fill
- Zoom images by percent when in full screen mode or
when window geometry is fixed. When combined with
--auto-zoom
, zooming will be limited to the specified percent. Specifyingmax
is like setting--auto-zoom
, usingfill
makesfeh
zoom the image like the--bg-fill
mode.
MONTAGE MODE OPTIONS¶
These additional options can be used for index, montage and (partially) thumbnail mode.-a
,--alpha
int- When drawing thumbnails onto the background, set their transparency level to int (0 - 255).
-b
,--bg
file |trans
- Use file as background for your montage. With this option specified, the montage size will default to the size of file if no size restrictions were specified. Alternatively, if file is “trans”, the background will be made transparent.
-X
,--ignore-aspect
- By default, the montage thumbnails will retain their aspect ratios, while
fitting into thumb-width/-height. This options forces them to be the size
set by
--thumb-width
and--thumb-height
. This will prevent any empty space in the final montage. -H
,--limit-height
pixels- Limit the height of the montage.
-W
,--limit-width
pixels- Limit the width of the montage, defaults to 800 pixels.
If both
--limit-width
and--limit-height
are specified, the montage will be exactly width x height pixels in dimensions. -o
,--output
file- Save the created montage to file.
-O
,--output-only
file- Just save the created montage to file without displaying it.
-s
,--stretch
- Normally, if an image is smaller than the specified thumbnail size, it
will not be enlarged. If this option is set, the image will be scaled up
to fit the thumbnail size. Aspect ratio will be maintained unless
--ignore-aspect
is specified. -E
,--thumb-height
pixels- Set thumbnail height.
-y
,--thumb-width
pixels- Set thumbnail width.
INDEX AND THUMBNAIL MODE OPTIONS¶
In addition to MONTAGE MODE OPTIONS--alpha
, --bg
,
--limit-height
, --limit-width
,
--output
, --output-only
,
--thumb-height
, --thumb-width
,
the following options can be used.
--index-info
format- Show image information based on format below
thumbnails in index / thumbnail mode. See
FORMAT SPECIFIERS. May contain
newlines. Use “--index-info ''” to display thumbnails
without any info text
Note: If you specify image-related formats (such as %w or %s),
feh
needs to load all images to calculate the dimensions of its own window. So when using them with many files, it will take a while before afeh
window becomes visible. Use--preload
to get a progress bar. -@
,--title-font
font- Set font to print a title on the index, if no font is specified, no title will be printed.
-J
,--thumb-redraw
n- Redraw thumbnail window every n images while generating thumbnails. Redrawing takes quite long, so the default is 10. Set n = 1 to update the thumbnail window immediately. With n = 0, there will only be one redraw once all thumbnails are loaded.
BACKGROUND SETTING¶
In many desktop environments,feh
can also be used as a
background setter. Unless you pass the --no-fehbg
option, it will write a script to set the current background to
~/.fehbg. So to have your background restored every
time you start X, you can add “~/.fehbg &” to your X startup
script (such as ~/.xinitrc).
Note that feh
does not support setting the
wallpaper of GNOME shell desktops. In this environment, you can use
“gsettings set org.gnome.desktop.background picture-uri
file:///path” instead.
For --bg-center
,
--bg-fill
, and --bg-max
, you
can use --geometry
to specify an offset from one
side of the screen instead of centering the image. Positive values will
offset from the left/top side, negative values from the bottom/right. +0 and
-0 are both valid and distinct values.
Note that all options except --bg-tile
support Xinerama. For instance, if you have multiple screens connected and
use e.g. --bg-center
, feh
will center or appropriately offset the image on each screen. You may even
specify more than one file, in that case, the first file is set on screen 0,
the second on screen 1, and so on.
Use --no-xinerama
to treat the whole X
display as one screen when setting wallpapers. You may also use
--xinerama-index
to use feh
as a background setter for a specific screen.
--bg-center
- Center the file on the background. If it is too small, it will be
surrounded by a border as specified by
--image-bg
. --bg-fill
- Like
--bg-scale
, but preserves aspect ratio by zooming the image until it fits. Either a horizontal or a vertical part of the image will be cut off --bg-max
- Like
--bg-fill
, but scale the image to the maximum size that fits the screen with borders on one side. The border color can be set using--image-bg
. --bg-scale
- Fit the file into the background without repeating it, cutting off stuff or using borders. But the aspect ratio is not preserved either
--bg-tile
- Tile (repeat) the image in case it is too small for the screen
--no-fehbg
- Do not write a ~/.fehbg file
FORMAT SPECIFIERS¶
- %f
- Image path/filename
- %F
- Escaped image path/filename (for use in shell commands)
- %g
- w,h window dimensions in pixels (mnemonic: geometry)

CONFIGURATION¶
feh
has three config files:
themes for theme definitions,
keys for key bindings and
buttons for mouse button bindings. It will try to read
them from $XDG_CONFIG_HOME/feh/, which (when
XDG_CONFIG_HOME is unset) defaults to ~/.config/feh/.
If the files are not found in that directory, it will also try
/etc/feh/.
All config files treat lines starting with a “#” character as comments. Comments at the end of a line are not supported.
THEMES CONFIG SYNTAX¶
.config/feh/themes allows the naming of option groups, called themes.It takes entries of the form “theme options ...”, where theme is the name of the entry and options are the options which will be applied when the theme is used.
Note that the option parser does not behave like a normal shell: filename expansion and backslash escape sequences are not supported and passed to feh's option parser as-is. However, quoting of arguments is respected and can be used for arguments with whitespace. So, the sequence “--info “foo bar”” works as intended (that is, it display the string “foo bar”), whereas the option string “--info foo\ bar” will only display “foo\” and complain about the file bar not existing. Please keep this in mind when writing theme files.
An example entry is “imagemap -rVq --thumb-width 40 --thumb-height 30 --index-info '%n\n%wx%h'”.
You can use this theme in two ways. Either call
“feh
-Timagemap *.jpg”, or create a
symbolic link to feh
with the name of the theme you
want it to use. For the example above, this would be “ln -s `which
feh
` ~/bin/imagemap”. Now just run
“imagemap *.jpg” to use these options.
Note that you can split a theme over several lines by placing a backslash at the end of an unfinished line. A single option-argument-pair must not span multiple lines. A single line must not be longer than 1023 characters, but there's no upper limit for the length of a theme.
Command line options always override theme options.
KEYS CONFIG SYNTAX¶
.config/feh/keys defines key bindings. It has entries of the form “action [key1 [key2 [key3]]]”.Each key is an X11 keysym name as shown by xev(1), like “Delete”. It may optionally start with modifiers for things like Control, in which case key looks like mod-keysym (for example “C-Delete” for Ctrl+Delete or “C-1-Delete” for Ctrl+Alt+Delete)
Available modifiers are C for Control, S for Shift and 1, 4 for Mod1 and Mod4. To match an uppercase letter like “S” instead of “s”, the Shift modifier is not required.
Specifying an action without any keys unbinds it (i.e. the default bindings are removed).
Note: Do not use the same keybinding for
multiple actions. When binding an action to a new key (or mouse button),
make sure to unbind it from its previous action, if present.
feh
does not check for conflicting bindings, so
their behaviour is undefined.
For a list of the action names, see KEYS. Note that not all of the key names used there correspond to X11 keysyms. Most notably, page up (Prior / Page_Up), page down (Next / Page_Down) and the keypad keys (KP_*) do not.
KEYS¶
The following actions and default key bindings can be used in an image window. (The strings in [square brackets] are the config action names). Iffeh
is running inside a terminal and its standard
input is not used for images or filelists, key input from the terminal is also
accepted. However, terminal input support is currently limited to most
alphanumeric characters (0-9 a-z A-Z and some more), arrow keys, return and
backspace. The Alt (Mod1) modifier is also supported.
- a [toggle_actions]
- Toggle actions display (see
--draw-actions
) - A [toggle_aliasing]
- Enable/Disable anti-aliasing
- c [toggle_caption]
- Caption entry mode. If
--caption-path
has been specified, then this enables caption editing. The caption at the bottom of the screen will turn yellow and can be edited.

When
--edit
is used, this also rotates the image in the underlying file. Rotation is lossless, but may create artifacts in some image corners when used with JPEG images. Rotating in the reverse direction will make them go away. See jpegtran(1) for more about lossless JPEG rotation. Note:feh
assumes that this feature is used to normalize image orientation. For JPEG images, it will unconditionally set the EXIF orientation tag to 1 (“0,0 is top left”) after every rotation. See jpegexiforient(1) for details on how to change this flag. - _ [flip]

MENU KEYS¶
The following keys bindings are used for thefeh
menu:
- ⟨Escape⟩ [menu_close]
- Close the menu
- ⟨Up⟩ [menu_up]
- Highlight previous menu item
- ⟨Down⟩ [menu_down]
- Highlight next menu item
- ⟨Left⟩ [menu_parent]
- Highlight parent menu item
- ⟨Right⟩ [menu_child]
- Highlight child menu item
- ⟨Return⟩, ⟨space⟩ [menu_select]
- Select highlighted menu item
BUTTONS CONFIG SYNTAX¶
.config/feh/buttons. This works like the keys config file: the entries are of the form “action [binding]”.Each binding is a button number. It may optionally start with modifiers for things like Control, in which case binding looks like mod-button (for example C-1 for Ctrl + Left button).
Note: Do not use the same button for multiple
actions. feh
does not check for conflicting
bindings, so their behaviour is undefined. Either unbind the unwanted
action, or bind it to another unused button. The order in which you bind /
unbind does not matter, though.
For the available modifiers, see KEYS CONFIGURATION SYNTAX.
BUTTONS¶
In an image window, the following buttons may be used (The strings in [square brackets] are the config action names). Additionally, all actions specified in the KEYS section can also be bound to a button.- unbound [reload]
- Reload current image
- 1 ⟨left mouse button⟩ [pan]
- pan the current image
- 2 ⟨middle mouse button⟩ [zoom]
- Zoom the current image
- 3 ⟨right mouse button⟩ [toggle_menu]
- Toggle menu
- 4 ⟨mousewheel down⟩ [prev_img]
- Show previous image
- 5 ⟨mousewheel up⟩ [next_img]
- Show next image
- Ctrl+1 [blur]
- Blur current image
- Ctrl+2 [rotate]
- Rotate current image
- unbound [zoom_in]
- Zoom in
- unbound [zoom_out]
- Zoom out
MOUSE ACTIONS¶
Default Bindings: When viewing an image, mouse button 1 pans the image (moves it around) or, when only clicked, moves to the next image (slideshow mode only). Quick drags with less than 2px of movement per axis will be treated as clicks to aid graphics tablet users. Mouse button 2 zooms (click and drag left->right to zoom in, right->left to zoom out, click once to restore zoom to 100%) and mouse button 3 opens the menu.Ctrl+Button 1 blurs or sharpens the image (drag left to blur, right to sharpen); Ctrl+Button 2 rotates the image around the center point.
A note about pan and zoom modes: In pan mode, if you reach a
window border but haven't yet panned to the end of the image,
feh
will warp your cursor to the opposite border so
you can continue panning.
When clicking the zoom button and immediately releasing it, the image will be back at 100% zoom. When clicking it and moving the mouse while holding the button down, the zoom will be continued at the previous zoom level. The zoom will always happen so that the pixel on which you entered the zoom mode remains stationary. So, to enlarge a specific part of an image, click the zoom button on that part.
SIGNALS¶
In slideshow mode,feh
handles the following signals:
USAGE EXAMPLES¶
Here are some examples of useful option combinations. See also: ⟨https://feh.finalrewind.org/examples/⟩- feh ~/Pictures
- Show all images in ~/Pictures
- feh -r ~/Pictures
- Recursively show all images found in ~/Pictures and subdirectories
- feh -rSfilename --version-sort ~/Pictures
- Same as above, but sort naturally. By default, feh will show files in the string order of their names, meaning e.g. “foo 10.jpg” will come before “foo 2.jpg”. In this case, they are instead ordered as a human would expect.
- feh -t -Sfilename -E 128 -y 128 -W 1024 ~/Pictures
- Show 128x128 pixel thumbnails, limit window width to 1024 pixels.
- feh -t -Sfilename -E 128 -y 128 -W 1024 -P -C /usr/share/fonts/truetype/ttf-dejavu/ -e DejaVuSans/8 ~/Pictures
- Same as above, but enable thumbnail caching and use a smaller font.
- feh -irFarial/14 -O index.jpg ~/Pictures
- Make an index print of ~/Pictures and all directories below it, using 14 point Arial to write the image info under each thumbnail. Save the image as index.jpg and don't display it, just exit. Note that this even works without a running X server
- feh --unloadable -r ~/Pictures
- Print all unloadable images in ~/Pictures, recursively
- feh -f by_width -S width --reverse --list .
- Write a list of all images in the directory to by_width, sorted by width (widest images first)
- feh -w ~/Pictures/holidays
- Open each image in ~/Pictures/holidays in its own window
- feh -FD5 -Sname ~/Pictures/presentation
- Show the images in .../presentation, sorted by name, in fullscreen, automatically change to the next image after 5 seconds
- feh -rSwidth -A “mv %F ~/images/%N” ~/Pictures
- View all images in ~/Pictures and below, sorted by width, move an image to ~/image/image_name when enter is pressed
- feh --start-at ~/Pictures/foo.jpg
- View all images in ~/Pictures, starting with foo.jpg. All other images are still in the slideshow and can be viewed normally
- feh --start-at ~/Pictures/foo.jpg ~/Pictures
- Same as above.
- feh --info "exifgrep '(Model|DateTimeOriginal|FNumber|ISO|Flash)' %F | cut -d . -f 4-" .
- Show some EXIF information, extracted by exifprobe/exifgrep
- feh --action 'rm %F' -rl --max-dimension 1000x800
- Recursively remove all images with dimensions below or equal to 1000x800 pixels from the current directory.
- feh -L '%w %h %f' | awk '{ if ($1 > $2) { print $0 } }' | cut -d ' ' -f 3- | feh -f -
- Show landscape pictures (image width greater than height) in the current directory.
DEPENDENCIES¶
When--edit
is used, feh
needs
the jpegtran
and
jpegexiforient
binaries (usually distributed in
“libjpeg-progs” or similar) for lossless JPEG rotation.
To view images from URLs such as "http://",
feh
must be compiled with libcurl support. It is
enabled in this build
KNOWN BUGS¶
On systems with giflib 5.1.2,feh
may be unable to load
gif images. For affected mips, mipsel and arm devices, gif support is
completely broken, while on x86 / x86_64 gifs can usually only be loaded if
they are the first image in the filelist. This appears to be a bug in giflib,
see ⟨https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=813729⟩
for details. Workaround: Use --conversion-timeout 5
(or some other positive value) to load gifs with imagemagick instead, or
downgrade to giflib 5.1.1, or upgrade to giflib 5.1.4.
While loading images using libcurl, feh
will not react to key or mouse actions.
Thumbnail mode is somewhat inefficient, and because of that not nearly as fast as it could be.
--scale-down
does not take window
decorations into account and may therefore make the window slightly too
large.
REPORTING BUGS¶
If you find a bug, please report it to ⟨derf+feh@finalrewind.org⟩ or via ⟨https://github.com/derf/feh/issues⟩. You are also welcome to direct any feh-related comments/questions/... to #feh on irc.oftc.net.Please include the feh version ⟨the output of “feh --version”⟩, steps to reproduce the bug and, if necessary, images to reproduce it.
FUTURE PLANS¶
Plans for the following releases:- Make zoom options more intuitive
