# Scrot: Linux command-line screen grabs made simple

> Scrot is a basic, flexible tool that offers a number of handy options for taking screen captures from the Linux command line.

[][1]
|
|
|
|
|
|
|
|
There are great tools on the Linux desktop for taking screen captures, such as [KSnapshot][2] and [Shutter][3]. Even the simple utility that comes with the GNOME desktop does a pretty good job of capturing screens. But what if you rarely need to take screen captures? Or you use a Linux distribution without a built-in capture tool, or an older computer with limited resources?
|
|
|
|
Turn to the command line and a little utility called [Scrot][4]. It does a fine job of taking simple screen captures, and it includes a few features that might surprise you.
|
|
|
|
### Getting started with Scrot
|
|
Many Linux distributions come with Scrot already installed—to check, type `which scrot`. If it isn't there, you can install Scrot using your distro's package manager. If you're willing to compile the code, grab it [from GitHub][5].
|
|
|
|
To take a screen capture, crack open a terminal window and type `scrot [filename]`, where `[filename]` is the name of file to which you want to save the image (for example, `desktop.png`). If you don't include a name for the file, Scrot will create one for you, such as `2017-09-24-185009_1687x938_scrot.png`. (That filename isn't as descriptive it could be, is it? That's why it's better to add one to the command.)
|
|
|
|
Running Scrot with no options takes a screen capture of your entire desktop. If you don't want to do that, Scrot lets you focus on smaller portions of your screen.
|
|
|
|
### Taking a screen capture of a single window
|
|
|
|
Tell Scrot to take a screen capture of a single window by typing `scrot -u [filename]`.
|
|
|
|
The `-u` option tells Scrot to grab the window currently in focus. That's usually the terminal window you're working in, which might not be the one you want.
|
|
|
|
To grab another window on your desktop, type `scrot -s [filename]`.
|
|
|
|
The `-s` option lets you do one of two things:
|
|
|
|
* select an open window, or
|
|
|
|
* draw a rectangle around a window or a portion of a window to capture it.
|
|
|
|
You can also set a delay, which gives you a little more time to select the window you want to capture. To do that, type `scrot -u -d [num] [filename]`.
|
|
|
|
The `-d` option tells Scrot to wait before grabbing the window, and `[num]` is the number of seconds to wait. Specifying `-d 5` (wait five seconds) should give you enough time to choose a window.
|
|
|
|
### More useful options
|
|
|
|
Scrot offers a number of additional features (most of which I never use). The ones I find most useful include:
|
|
|
|
* `-b` also grabs the window's border
|
|
|
|
* `-t` grabs a window and creates a thumbnail of it. This can be useful when you're posting screen captures online.
|
|
|
|
* `-c` creates a countdown in your terminal when you use the `-d` option.
|
|
|
|
To learn about Scrot's other options, check out the its documentation by typing `man scrot` in a terminal window, or [read it online][6]. Then start snapping images of your screen.
|
|
|
|
It's basic, but Scrot gets the job done nicely.
