Exiting a running Bash Script in Terminal
If for some reason a bash script is running too long and you want to exit its execution, then you can make press the keyboard keys Control + C.
Example:bash-3.2$ ./script.sh
^C
bash-3.2$
When you press Control + C you will see a ^C character displayed on the Terminal and you are returned back to the bash shell prompt.
Exiting a Script from within a Bash Script
On the other hand if you want to exit the script from within it, then you can make use of the exit 0 command. When this command is encountered while execution the script will terminal and return back to the prompt.
Example:#!/bin/bash
sleep 10
exit 0
echo "Hello there"
When you run the above script, it exits at line number 2, and the 3rd echo line is not printed.
