# man
**man** shows system manual pages.

There are 8 different sections to man:

* 1 -> **programs** *(grep, ls)*
* 2 -> [System calls](./System_Calls.md) *(sendfile, ptrace)*
* 3 -> **C functions** *(printf, fopen)*
* 4 -> **devices** *(null, tty)*
* 5 -> **file fomats** *(sudoers, proc, ext4, elf, fstab)*
* 6 -> **games** *(sl)*
* 7 -> **misc** *(concepts, ex: pipe, symlink)*
* 8 -> **sysadmin** *(apt, chroot)*


At ``/usr/share/man/man2`` you can view every manpage for that section.
