screenkey:tldr:b9da5
The command you provided is a Linux shell command that uses two different programs, slop
and screenkey
, together.
Here's an explanation of each part of the command:
-
slop -n -f '%g'
: This part of the command runs theslop
program and specifies some options.slop
is a tool for selecting an area on the screen and outputting its geometry (width and height). The options-n
tellsslop
not to print the selected rectangle, and-f '%g'
specifies the format of the output, it will only print the geometry. -
${$(slop -n -f '%g')}
: The$()
syntax is used to capture the output of theslop
command and substitute it in place. So this part replaces${$(slop -n -f '%g')}
with the output ofslop
command, which is the width and height of the selected area on the screen. -
screenkey --position fixed --geometry ${$(slop -n -f '%g')}
: This part of the command runs thescreenkey
program with options--position fixed
and--geometry
.screenkey
is a tool that displays key presses on the screen, useful for screen recordings or presentations.--position fixed
specifies that the key display should be fixed on a certain position, and--geometry
specifies the size and position of the key display on the screen.
Overall, this command is used to execute screenkey
with a fixed position and size on the screen, using the output of slop
to determine the position and size dynamically based on the selected area.
