The purpose of the trap command in Bash is to allow scripts to catch and respond to signals and interruptions. It enables you to define specific actions that should be executed when certain signals are received, such as:
- SIGINT: Sent when the user interrupts the script (e.g., by pressing Ctrl+C).
- SIGTERM: Sent to request termination of the script.
By using trap, you can implement cleanup routines, save state, or perform other necessary actions before the script exits. This makes your scripts more robust and user-friendly by handling unexpected terminations gracefully.
