NAME¶
feh
—
image viewer and cataloguer
SYNOPSIS¶
feh |
[ options ]
files or directories or URLs ... |
VERSION¶
This manual documentsfeh
2.12
Compile-time switches: libcurl support enabled, Xinerama support enabled,
builtin EXIF support enabled
DESCRIPTION¶
feh
is a mode-based image viewer. It is
especially aimed at command line users who need a fast image viewer without
huge GUI dependencies, though it can also be started by (graphical) file
managers to view an image.
feh
supports filelists, various image sorting
modes, image captions, HTTP and more. Configurable keyboard shortcuts are used
to control it; the mouse is also supported, but only required for very few
actions.
feh
can also be used as wallpaper setter.
A little note about EXIF support: The recommended way to display EXIF data is
using exiv2 / exifgrep via --info
(see the
USAGE EXAMPLES
section). However, if you compile feh with exif=1, you
can also display it directly.
MODES¶
feh
is based on various modes, which are
selected at startup by command line options.
Slideshow mode is the default. It opens one window and displays the first image
in it, the keyboard and mouse can be used to change slides (images). In
slideshow mode, images can be deleted either from the filelist or from the
disk, the new filelist can then 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, filesize and pixel size, 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. Outputs an ls
-
style listing of the files in the filelist,
including image info such as size, pixels, type, etc. Customlist mode will
display whatever image info you want, in the format you choose.
feh
can also list either all the loadable
files in a filelist or all the unloadable files. Useful for preening a
directory.
SUPPORTED FORMATS¶
feh
can open any format supported by Imlib2,
most notably jpeg and png. If the convert binary (supplied by ImageMagick) is
available, it also has limited support for many other filetypes, such as svg,
xcf and otf. Use --magick-timeout
num with a non-negative value to enable it.
For animated images, only the first frame is shown.
OPTIONS¶
-A
,--action
[flag]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 after executing the action. The action will be executed by /bin/sh. Use format specifiers to refer to image info. See FORMAT SPECIFIERS for examples. E.g. “feh -A mv ~/images/%n *”. In slideshow mode, the next image will be shown after running the action, in multiwindow mode, the window will be closed. --action1
..--action9
- Extra actions which can be set and triggered using the appropriate number key.
-Z
,--auto-zoom
- Zoom pictures to screen size in fullscreen / fixed geometry mode.
-x
,--borderless
- Create borderless windows.
-P
,--cache-thumbnails
- Enable thumbnail caching in ~/.thumbnails. Only works with thumbnails <= 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”.
-L
,--customlist
format- Don't display images, print image info according to format instead. See FORMAT SPECIFIERS.
--cycle-once
- Exit
feh
after one loop through the slideshow. -G
,--draw-actions
- Draw the defined actions and what they do at the top-left of the image.
--draw-exif
- (only if compiled with exif=1) display some EXIF information in the bottom
left corner, similar to using
--info
with exiv2 / exifgrep . -d
,--draw-filename
- Draw the filename 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 -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
filenames, absolute or relative to the current directory, one filename 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 whenfeh
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 antialiasing 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,
--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, no matter their dimensions. -g
,--geometry
[width x height] [+ x + y]- Limit (and don't change) the window size. Takes an X-style geometry string like 640x480 with optional +x+y window offset. Note that larger images will be zoomed out to fit, but you can see them at 1:1 by clicking the zoom button. Note that this option does not enforce the geometry, changing it by a tiling WM or manually is still possible.
-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: checks, white, black. The default for windowed mode is checks, while fullscreen defaults to 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 MODE OPTIONS and MONTAGE MODE OPTIONS.
--index-info
format- Show image information based on format
below thumbnails in index / thumbnail mode. See
FORMAT SPECIFIERS.
May contain newlines.
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. --info
[flag]commandline- Execute commandline 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.
-k
,--keep-http
- When viewing files using HTTP,
feh
normally deletes the local copies after viewing, or, if caching, on exit. This option prevents this so that you get to keep the local copies. They will be in /tmp with “feh
” in the name. --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.
--magick-timeout
timeout- Stop trying to convert unloadable files after
timeout seconds. A negative value
disables covert / magick support altogether, a value of zero causes
feh
to try indefinitely. By default, magick support is disabled. --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 either something large or -1.
-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
- Disable Xinerama support. Only makes sense when you have Xinerama support compiled in.
-j
,--output-dir
directory- Save files to directory (only useful with -k)
-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 commandline arguments to the content of those directories, all the way down to the bottom level.
-R
,--reload
int- Reload filelist and current image after
int seconds. Useful for viewing HTTP
webcams or frequently changing directories. (Note that the 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
- When not in fullscreen: Scale images to screen size if they are too big. 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 inverse the scroll direction; see KEYS CONFIG SYNTAX to change 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- The file list may be sorted according to image parameters. Allowed sort types are: name, filename, mtime, width, height, pixels, size, format. For sort modes other than name, filename, or mtime, a preload run will be necessary, causing a delay proportional to the number of images in the list. The mtime sort mode sorts images by most recently modified. To sort by oldest first, reverse the filelist with --reverse.
-|
,--start-at
filename- Start the filelist at filename. See USAGE EXAMPLES.
-T
,--theme
theme- Load options from config file with name
theme - see
THEMES CONFIG
SYNTAX for more info. Note that commandline 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 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.
--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.
-J
,--thumb-redraw
n- Only relevant for
--thumbnails
: Redraw thumbnail window every n images. Infeh
<= 1.5, the thumbnail image used to be redrawn after every computed thumbnail (so, it updated immediately). However, since the redrawing takes quite long (especially for thumbnail mode on a large filelist), this turned out to be a major performance penalty. As a workaround, the thumbnail image is redrawn every 10th image now by default. Set n = 1 to get the old behaviour, n = 0 will only redraw once all thumbnails are loaded.
INDEX MODE OPTIONS¶
-@
,--title-font
font- Set font to print a title on the index, if no font is specified, no title will be printed.
BACKGROUND SETTING¶
feh
can also be used as a background setter.
Unless you pass the --no-fehbg
option, it
will store the command line necessary to set the background in
~/.fehbg, so to have your background
restored every time you start X, you can add “eval $(cat
~/.fehbg)” to your X startup script (like
~/.xinitrc).
For the --bg-center
and
--bg-max
options, you can use the
--geometry
option 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.
--bg-center
- Center the file on the background. If it is too small, it will be surrounded by a black border
--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 black borders on one side. --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)
- %h
- Image height
- %l
- Total number of files in filelist
- %L
- Temporary copy of filelist. Multiple uses of %L within the same format string will return the same copy.

- Image name
- %N
- Escaped image name
- %o
- x,y offset of top-left image corner to window corner in pixels
- %p
- Number of image pixels
- %P
- Number of image pixels (kilopixels / megapixels)
- %r
- Image rotation. A half right turn equals pi.
- %s
- Image size in bytes
- %S
- Human-readable image size (kB / MB)
- %t
- Image format
- %u
- Number of current file
- %w
- Image width
- %v
feh
version- %V
- Process ID
- %z
- current image zoom
- %%
- A literal %
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. Note that mid-line comments 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. An example entry would be “imagemap -rVq --thumb-width 40 --thumb-height 30”. 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. So from the example above: “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 a line, like in the shell.
You can combine these themes with commandline options.
KEYS CONFIG SYNTAX¶
.config/feh/keys defines key bindings. It has entries of the form “action [key1
[
]”.
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. key2
[
]key3
]feh
does not check for conflicting
bindings, so their behaviour is undefined. Either unbind the unwanted action,
or bind it to another unused key. The order in which you bind / unbind does
not matter, though.
For a list of the action names, see
KEYS.
KEYS¶
In an image window, the following keys may be used (The strings in [square brackets] are the config action names):- 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. Hit return to confirm and save the caption, or escape to cancel editing. Note that you can insert an actual newline into the caption using ⟨CTRL+return⟩. - d [toggle_filenames]
- Toggle filename display (see
--draw-filename
) - e [toggle_exif]
- (only if compiled with exif=1) Toggle EXIF tag display
- f [save_filelist]
- Save the current filelist as “feh_PID_ID_filelist”
- h [toggle_pause]
- Pause/Continue the slideshow. When it is paused, it will not automatically
change slides based on
--slideshow-delay
. - i [toggle_info]
- Toggle info display (see
--info
) - k [toggle_keep_vp]
- Toggle zoom and viewport keeping. When enabled,
feh
will keep zoom and X, Y offset when switching images. - m [toggle_menu]
- Show menu. Use the arrow keys and return to select items, ⟨escape⟩ to close the menu.
- n, ⟨Space⟩, ⟨Right⟩ [next_img]
- Show next image
- o [toggle_pointer]
- Toggle pointer visibility
- p, ⟨Backspace⟩, ⟨Left⟩ [prev_img]
- Show previous image
- q, ⟨Escape⟩ [quit]
- Quit
feh
- r [reload_image]
- Reload current image. Useful for webcams
- s [save_image]
- Save the current image as “feh_PID_ID_FILENAME”
- v [toggle_fullscreen]
- Toggle fullscreen
- w [size_to_image]
- Change window size to fit current image size
- x [close]
- Close current window
- z [jump_random]
- Jump to a random position in the current filelist
- <, > [orient_3, orient_1]
- In place editing - rotate the images 90 degrees (counter)clockwise. The
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: jpegtran does not update
EXIF orientation tags. However,
feh
assumes that you use the feature to normalize image orientation and want it to be displayed this way everywhere. After every rotation, it will unconditionally set the EXIF orientation to 1 (“0,0 is top left”). Should you need to reverse this, see jpegexiforient(1). - _ [flip]
- In place editing - vertical flip
- | [mirror]
- In place editing - horizontal flip. Again, see jpegtran(1) for more information.
- 0 .. 9 [action_0 .. action_9]

--action
, 1 =--action1
etc.) - ⟨Return⟩ [action_0]
- Run the command defined by
--action
- ⟨home⟩ [jump_first]
- Show first image
- ⟨end⟩ [jump_last]
- Show last image

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 name. 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):- [reload]

- 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: ⟨http://feh.finalrewind.org/examples/⟩- feh /opt/images
- Show all images in /opt/images
- feh -r /opt/images
- Recursively show all images found in /opt/images and subdirectories
- feh -rSfilename /opt/images
- Same as above, but sort by filename. By default, feh will show files in the order it finds them on the hard disk, which is usually somewhat random.
- feh -t -Sfilename -E 128 -y 128 -W 1024 /opt/images
- 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 /opt/images
- Same as above, but enable thumbnail caching in ~/.thumbnails and use a smaller font.
- feh -irFarial/14 -O index.jpg /opt/images
- Make an index print of /opt/images 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 /opt/images
- Print all unloadable images in /opt/images, 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 /opt/images/holidays
- Open each image in /opt/images/holidays in its own window
- feh -FD5 -Sname /opt/images/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” /opt/images
- View all images in /opt/images and below, sorted by width, move an image to ~/image/image_name when enter is pressed
- feh --start-at ./foo.jpg .
- View all images in the current directory, starting with foo.jpg. All other images are still in the slideshow and can be viewed normally
- feh --start-at foo.jpg *
- 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-dim 1000x800
- Resursively remove all images with dimensions below or equal to 1000x800 pixels from the current directory.
TILING WINDOW MANAGERS¶
feh
was created with a floating window layout
in mind. However, as of 2.0.1, it has limited support for tiling window
managers.
Specifically, the --scale-down
and --auto-zoom
options will detect a tiling environment and scale the image up / down to the
current window size. Unfortunately, this causes every image to be rendered
twice: First in a normal fashion, and then (after noticing that the window is
being tiled) again with the correct zoom level.
This is a known bug and will hopefully get fixed some time. For now, it can be
avoided by using --geometry 500x500
(or any
other geometry). This will have the same behaviour as
--scale-down
, but without the flickering.
DEPENDENCIES¶
feh
requires the
jpegtran
and
jpegexiforient
binaries (usually
distributed in “libjpeg-progs” or similar) for lossless
rotation.
To view images from URLs such as http://, you need
feh
compiled with libcurl support (enabled
by default). See the VERSION
section.
BUGS¶
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 ⟨http://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
