Linux Usage Notes

With most Linux or Unix commands;

• Non root users may need to prefix commands with the sudo command, for example: sudo chmod 644 *
• Brief help can be displayed using the -h or --help parameter, for example: chmod --help
• A full command manual can be displayed using the man command followed by the command name, for example: man chmod
• Sometimes 'info' pages are used instead of or to provide more information than man pages; for example: info chmod
• Version information can normally be display using the -v, -V or --version parameter, for example: chmod --version. However, this paramater is also frequently used to display verbose output.
