NAME¶scrot - command line screen capture utility
scrot [options] [file]
DESCRIPTION¶scrot (SCReenshOT) is a simple command line screen capture utility that uses imlib2 to grab and save images. Multiple image formats are supported through imlib2's dynamic saver modules.
Some features of the scrot:
- support to multiple image formats (JPG, PNG, GIF, etc.).
- optimization of the screen shots image quality.
- capture a specific window or a rectangular area on the screen with the help of switch.
scrot also can be used to monitor a desktop PC in admin absent and register unwanted activities.

- -d, --delay NUM
- Wait NUM seconds before taking a shot.
- -e, --exec APP

- -q, --quality NUM
- Image quality (1-100) high value means high size, low compression. Default: 75. (Effect differs depending on file format chosen).

- -s, --select

- -u, --focused

- -z, --silent
- Prevent beeping.
- -p, --pointer
- Capture the mouse pointer.
- -o, --overwrite

SPECIAL STRINGS¶Both the --exec and filename parameters can take format specifiers that are expanded by scrot when encountered. There are two types of format specifier. Characters preceded by a '%' are interpreted by strftime(2). See man strftime for examples. These options may be used to refer to the current date and time. The second kind are internal to scrot and are prefixed by '$' The following specifiers are recognised:
$a hostname $f image path/filename (ignored when used in the filename) $m thumb image path/filename (ignored when used in the filename) $n image name (ignored when used in the filename) $s image size (bytes) (ignored when used in the filename) $p image pixel size $w image width $h image height $t image format (ignored when used in the filename) $$ print a literal '$' \n print a newline (ignored when used in the filename)Example:
$ scrot '%Y-%m-%d_$wx$h.png' -e 'mv $f ~/shots/'This would create a file called something like 2000-10-30_2560x1024.png and move it to your shots directory.
SELECTION STYLE¶When using --select you can indicate the style of the line with --line.
The following specifiers are recognised:
style=(solid,dash),width=(range 1 to 8),color="value", opacity=(range 10 to 100),mode=(edge,classic)The default style is:
mode=classic,style=solid,width=1,opacity=100Mode 'edge' ignore: style, --freeze
Mode 'classic' ignore: opacity
The 'opacity' specifier is only effective if a Composite Manager is running.
For the color you can use a name or a hexadecimal value.
color="red" or color="#ff0000"Example:
$ scrot --line style=dash,width=3,color="red" --select
NOTE FORMAT¶The following specifiers are recognised for the option --note:
-f 'FontName/size' -t 'text' -x position (optional) -y position (optional) -c color(RGBA) (optional) -a angle (optional)Example:
$ scrot --note "-f '/usr/share/fonts/TTF/DroidSans-Bold/40' -x 10 -y 20 -c 255,0,0,255 -t 'Hi'"
