Problem Description
In Bash, errors can occur during script execution due to various reasons, such as invalid input, missing files, or unexpected issues. To gracefully handle these errors and ensure robust scripts, you need to employ error-handling techniques.
Is there a TRY CATCH command in Bash?
Bash is a powerful scripting language used in the Unix and Linux environments, primarily for automating tasks and scripting. While Bash doesn’t have a built-in ‘TRY CATCH’ command like some other programming languages, you can achieve similar functionality using a combination of ‘trap’, the ‘-x’ flag for tracing, and conditional logic. In this article, we will explore how to emulate a ‘TRY CATCH’ behavior in Bash, trace output with the ‘-x’ flag, and force an exit when an error is detected.
