When scripting in Bash, managing how your script handles errors can influence the robustness and reliability of your automation efforts. In this article, we delve into how to effectively control error handling by setting traps for specific commands within a Bash script. Q1: What is a trap in Linux Bash? A1: In Bash, a trap is a function that can be triggered when certain signals or events occur in a script. Essentially, it can "catch" signals (like SIGINT or SIGTERM) or specific conditions such as ERR for errors, allowing the script to execute a predefined set of instructions when these events happen.
