Documents the Linux kernel system calls and C library interfaces used
by programs, plus system and administrative utilities, devices, file
system, file, and data formats, and related information.
For more information, see the project home page:
https://kernel.org/doc/man-pages/
As Cygwin has its own man pages with some conflicts, these man pages are
installed under /usr/share/man/man-pages-linux/, so by default searching
or viewing these pages requires the option:
$ apropos -m|--systems man-pages-linux ...
$ man -m|--systems man-pages-linux ...
Cygwin man pages are under the default system "man", so for convenience
both systems may be specified separated by comma e.g.
$ man -m man,man-pages-linux ...
The path or option may also be added explicitly to a user's MANPATH or
alias e.g.
$ export MANPATH=$MANPATH:/usr/share/man/man-pages-linux
$ alias apropos='apropos -m man,man-pages-linux'
$ alias man='man -m man,man-pages-linux'
Add -a to show both Cygwin and Linux (and POSIX if companion package
man-pages-posix is also installed) manual pages.
For convenience and backward compatibility /usr/share/man/linux is
provided as a symlink.
If you prefer to see Linux man pages over Cygwin man pages, then use
-m|--systems linux in the examples above, or add -m linux to a command.
Release 6 and later added some section 2 and 3 pages suffixed by const,
head, or type installed in the base section directories.
The following package has been upgraded in the Cygwin distribution:
- man-pages-linux 6.16
