Introduction In the world of scripting and automation, understanding exit codes is paramount. Exit codes, also known as return codes, are numerical values that a program or script returns upon completion, signaling success or failure. Mastering exit codes allows for robust error handling, efficient automation, and seamless integration within larger systems. This comprehensive guide will equip you with the knowledge to effectively utilize exit codes in your scripting endeavors, regardless of your chosen language. Understanding Exit Codes Exit codes are typically integers, ranging from 0 to 255. The most common convention is: 0: Indicates successful execution. Non-zero: Indicates an error, with the specific number often representing a particular error type. The meaning of non-zero exit codes is often language- or application-specific. This simple yet powerful mechanism allows scripts to communicate their status to their parent processes or the operating system. This inform...
