Exit statuses in Bash scripts are integral for error handling and control flow. They’re numerical codes returned by every command upon completion, indicating success (0) or failure (non-zero). Scripts can utilize these to make decisions; a common practice is using ‘if’ statements to check the exit status of a command and perform actions based on that. For instance, if a file deletion command fails, the script might log an error message and terminate. This allows for robust scripts capable of self-diagnosis and recovery from unexpected situations.
