Exit Code

Description: The ‘Exit Code’ is a number returned by a command in operating systems and programming environments to indicate the result of executing that command. This code is fundamental in script programming and task automation, as it allows developers and system administrators to determine whether a command executed successfully or if an error occurred. By convention, an exit code of ‘0’ indicates success, while any other number generally represents a specific type of error. Exit codes are especially relevant in continuous integration environments, where they are used to evaluate the status of software tests and builds. In various operating systems, handling exit codes is a common practice in shell scripts, enabling the creation of more robust and reliable workflows. Additionally, in security contexts, exit codes can influence the execution of applications, ensuring that only those that have passed certain checks are run.
