Capture the Entire Desktop

The simplest way to use Scrot is capturing the complete desktop. This command captures the entire screen content and saves it as an image file in the current directory with a timestamped filename.

Basic Full Screen Capture

Capture with Custom Filename

Capture with Quality Settings

scrot -q 75 screenshot_%Y%m%d_%H%M%S.jpg

The %Y%m%d_%H%M%S format creates timestamps like 20241201_143022 for easy organization.

Capture a Specific Region

Scrot can capture specific regions of the screen using the -s (select) option. This enters interactive selection mode where you can click and drag to define the area to capture.

Interactive Region Selection

Window Selection

The -u option captures the currently focused window, while -s allows manual selection of any rectangular area on the screen.

Add a Delay Before Capturing

The delay functionality allows you to prepare your screen or navigate to a specific application before the screenshot is taken. Use the -d option followed by the number of seconds to wait.

Delay Examples

# Wait 5 seconds before capturing
scrot -d 5 delayed_screenshot.png

# Combine delay with region selection
scrot -d 3 -s delayed_region.png

# Delay with window capture
scrot -d 2 -u delayed_window.png
