man

Additional Notes

man is a help command used to read manual pages for commands and system interfaces. It provides comprehensive reference documentation for commands, system calls, libraries, and file formats.

Manual pages are organized into numbered sections (1-8). Use man SECTION TOPIC to access a specific section, for example man 5 crontab for the configuration file format.

Syntax

Parameters

Manual pages are detailed but compact. Inside man, use / to search and q to quit.
