The trap command can be used to set up a signal handler that will execute a script when a specific signal is received by the shell. One useful application of this is to automatically remove any temporary files that have been created during the execution of the script. By setting a trap for the appropriate signal (such as SIGINT or SIGTERM) and including a command to remove the files in the handler script, you can ensure that cleanup is performed automatically when the script finishes or is interrupted.
