About:
GNU getopt is a command-line utility that parses command-line options and arguments, providing standardized handling of flags and parameters. It is part of the util-linux package and offers both short and long option support, making it a robust choice for shell scripting.
Key Features:
  • Supports both short (-a) and long (--all) option formats
  • Handles option arguments, optional arguments, and required arguments
  • Generates standardized error messages for invalid inputs
  • Provides shell script integration for robust CLI parsing
Use Cases:
  • Parsing user input in shell scripts (sh/bash/zsh)
  • Standardizing CLI interfaces for custom utilities
  • Validating and processing command-line flags in automation workflows
Alternatives:
  • getopts (shell builtin) – Simpler but limited to short options; no long option support
  • python-argparse – More powerful for complex CLIs but requires Python runtime
