Bash Script: Delete characters in string up to and including a phrase?

I have a bash script for hiding X11 windows. I want to be able to find what window the mouse is positioned over and unmap that window.

Using xdotool I've gotten a way to find the window ID:

$ xdotool getmouselocation
x:392 y:344 screen:0 window:54799020

I want to trim this line to just 54799020.
(I want to remove everything up to and including window:.)

Is there a way to do this? I have very little experience with tr and sed. I've used sed to remove text before, but I need to also remove the mouse coordinates, which are not always the same.

Solution

  • Try this,

    sed 's/.*window:\(.*\)/\1/g' file

    In your case,

    xdotool getmouselocation | sed 's/.*window:\(.*\)/\1/g'

    Example:

    $ echo "x:392 y:344 screen:0 window:54799020" | sed 's/.*window:\(.*\)/\1/g'
54799020
