Description: Bash exit codes are numerical values returned by commands to indicate success or failure. These codes are fundamental in script programming and system administration, as they allow users and other programs to know the result of executing a command. By convention, an exit code of ‘0’ indicates that the command executed successfully, while any other number generally indicates an error or unexpected result. Exit codes are an essential feature of Unix-like systems and their derivatives, such as Bash, and are used in most Unix-based operating systems. The interpretation of these codes is crucial for control flow in scripts, allowing developers to make decisions based on the success or failure of previous commands. Additionally, exit codes can be used for debugging scripts, facilitating the identification of issues in command execution. In summary, Bash exit codes are a powerful tool that provides information about the execution state of commands, enabling more efficient and effective task management in the command-line environment.
