Man Pages are basically manual pages mostly found in Unix or Unix-like operating systems. These pages are called “Man Pages” since these are read with man command. These pages are usually pre-installed in the computer systems.
Man Pages Sections
Manual pages are broadly divided in eight (8) major categories ( check the table below ). You can find their section numbers on top of man pages in brackets. For example in LS (1) for ls command man page. It means ls command is a user level or application level command.
|1||User-level commands and applications OR General Commands|
|2||System Calls and Kernel error codes|
|4||Device drivers and Network protocols|
|5||File formats and Conventions|
|6||Games and demonstrations|
|7||Miscellaneous files and documents|
|8||System Administration Commands and Daemons|
In some systems, there are also few others sections like section-9 for Kernel Specs and Interfaces. There is a considerable difference in the exact distribution of man pages, however, it is not a problem since man command finds appropriate page wherever relevant pages are stored.
