Linux process status codes, often referred to as exit codes, are numerical values returned by a process upon its termination. These codes indicate whether the process completed successfully or encountered an error; for instance, a code of 0 typically signifies success, while any non-zero value indicates different types of errors. Developers can use these codes to diagnose issues or determine the outcome of executed commands. Common status codes include 1 for general errors, 2 for misuse of shell builtins, and 127 for command not found.
