Automatically reload command in terminal after its run?

[doudou8310]

Hi,

I am using the following command in Terminal [screencapture -D2 "path to save folder"`date +%Y-%m-%d_%H-%M-%S`".png"] to take several screencaps rapidly one after the other.

Right now, to repeat the command, I use up arrow, then enter.

Wondering if there would be a simple way for the line of command to be automatically reloaded in the next line (after its run) so that pressing enter would be the only action needed to take another screencap?

A shell script could do it. Something like this using the 'a' key as a trigger :

#!/bin/bash



while true; do

read -rsn1 input

if [ "$input" = "a" ]; then

screencapture -D2 "path to save folder"`date +%Y-%m-%d_%H-%M-%S`".png"

fi

done
