There some scripts that need human interaction from time to time from confirming certain actions or to warn users that they are about to do something stupid ( “ rm -rf / “, perhaps?). In any case, putting a pause break in a Bash script is a very nifty trick to learn.

This is an example of how to use the Bash built-in command read to put pauses in scripts:

#!/bin/bash

find /home -type f -name "*.txt" read -p "Press [enter] key to delete *.txt files in /home or CTRL+C to exit" find /home -type f -name "*.txt" | xargs rm -v

This example script will run the find command and display the results. If user presses the Enter key, the script will remove all files that were found, while pressing CTRL+C will terminate the script.

Here is another variation of the the script:

#!/bin/bash

find /home -type f -name "*.txt" echo "Press [enter] key to delete *.txt files in /home or CTRL+C to exit" read contscr find /home -type f -name "*.txt" | xargs rm -v
