What is the terminal command to take a screenshot?

Question

What command(s) can I use in the terminal that's equivalent to the PrtSc (Print Screen) button?

I am running Ubuntu GNOME.

Answer 1

You can use import tool available in the ImageMagick package (you need to install this if its already not available on your system).

Run the following command in a shell:

import screenshot.png

and select the window you want to capture or select a region by pressing the left mouse button and dragging.

import is a actually a very powerful command which can be used in many ways to capture the screen. For example, to capture the entire screen and after some delay and resizing it, use the following command:

import -window root -resize 400x300 -delay 200 screenshot.png

To see all the options available with import command, go to ImageMagick’s website.

Another way to take a screenshot from the terminal is with scrot

To install scrot type:

sudo apt-get install scrot

To take a screenshot in Linux from the terminal with scrot type:

scrot MyScreenshot.png

Some more options with scrot are here:

scrot -b -d 5 '%Y:%m:%d:%H:%M:%S.png' -e 'mv $f ~/Desktop/'

In this example,

• -b specifies including the window borders
• -d specifies a delay of five seconds
• '%Y:%m:%d:%H:%M:%S.png' will save the screenshot with a name based on the current date and time and with the format specified, .png in this case
• -e 'mv $f ~/Desktop/' tells scrot to save the screenshot to the Desktop

Answer 2

Found this option here and other options are also listed.

Open terminal by pressing Ctrl + Alt + T and type

gnome-screenshot

use gnome-screenshot -d xx to delay the action.

To delay the screenshot action by 10s

gnome-screenshot -d 10

or

sleep 10;gnome-screenshot

            Capture the entire screen.

    -w, --window=[NAME_PATTERN]

            regex) ist optional.

    -a, --active
            Capture the current active window.

            by moving the mouse over it.

  Settings Options:

    -o, --output=FILENAME
            Specify a filename to save the screenshot to (overwrites any
            profile-related setting).

            Supported image formats: You can save to any popular image
            format (e.g. jpeg, png, gif, bmp). Additionally it is possible
            to save to pdf, ps or svg.

            Please note: There are several wildcards available, like

             %Y = year
             %m = month
             %d = day
             %T = time
             $w = width
             $h = height
             $name = multi-purpose (e.g. window title)
             $nb_name = like $name but without blanks in resulting strings
             $profile = name of current profile
             $R = random char (e.g. $RRRR = ag4r)
             %NN = counter

            The string is interpretted by strftime. See "man strftime" for
            more examples.

            As an example: shutter -f -e -o './%y-%m-%d_$w_$h.png' would
            create a file named '11-10-28_1280_800.png' in the current
            directory.

  Application Options:
    -h, --help
            Prints a brief help message and exits.

    -v, --version
            Prints version information.

    -d, --debug
            Prints a lot of debugging information to STDOUT.

    --clear_cache
            Clears cache, e.g. installed plugins, at startup.

    --min_at_startup
            Starts Shutter minimized to tray.

    --disable_systray
            Disables systray icon.

    -e, --exit_after_capture
            Exit after the first capture has been made. This is useful when
            using Shutter in scripts.

I tried using ImageMagick import but it didn't work for me when using KDE Desktop Effects. ImageMagick import has output transparent window borders in black instead of properly combining foreground alpha and background.

I also tried using X11 xwd and NetPBM xwdtopnm but that also didn't work for me, NetPBM xwdtopnm couldn't properly deal with the multiscreen output of xwd because I have a Xinerama setup.

But combining X11 xwd with ImageMagick convert worked just fine for me:

xwd -silent -root | convert xwd:- screenshot.png

Or, if you have a Dual-FullHD Xinerama setup, like me, and want the first screen only:

xwd -silent -root | convert xwd:- -crop 1920x1080+0+0 test.png

For the second screen only:

xwd -silent -root | convert xwd:- -crop 1920x1080+1920+0 +repage test.png

If you want to take a screenshot from a login-terminal (the one you open with Ctrl+Alt+F1) you can use the program fbgrab.

You can install it by typing sudo apt-get install fbcat.

Then take a screenshot of your login-terminal, type in your login-terminal:

$ sudo fbgrab my_screenshot

my_screenshot is saved under the current directory.

I'm using ubuntu 13.10 and I have a script that I just wrote which may be helpful. I see this questions been answered but my solution requires no additional installs.

#!/bin/bash
curDate=$(date)
imgExtension=".png"
imgName=$curDate$imgExtension
imgDirectory="/path/to/desires/save/directory/"
imgSavePath=$imgDirectory$imgName
gnome-screenshot --file="$imgSavePath"

This code will save the screenshot without popping up the dialogue window. It uses the current time for a file name to avoid any duplicate filename issues.
