script termination

The blog discusses how to handle the SIGTERM signal in Bash scripts to prevent abrupt termination during critical cleanup operations. Using the `trap` command, the article illustrates how to catch and manage SIGTERM to ensure vital tasks are completed successfully, thus avoiding data loss and promoting robust system behavior.

In Bash scripting, using the `exit` command within a function allows not only for the function to end, but also terminates the entire script. This is vital for managing errors effectively. By specifying an exit status, the script can signal success (0) or failure (non-zero values), crucial for interactions with other programs or scripts. Examples demonstrate ending scripts upon errors like missing files or failed network checks to prevent data corruption and ensure reliability.
