Where are man pages stored in Ubuntu?
Use manpath
to see the directories used by your system, and man --where --all foo
to find a specific manual page of foo.
The standard location is /usr/share/man
according to Filesystem Hierarchy Standard, and /usr/man
is usually a symlink to that directory.
Other locations can be defined in /etc/manpath.config
or /etc/man_db.conf
(exact location varies). For example, /usr/local/share/man is almost always included.
In addition, man tries to find manual pages for every directory specified in $PATH – for example, if you added /opt/plan9/bin to $PATH, man will automatically search /opt/plan9/man and /opt/plan9/bin/man.
If the $MANPATH
environment variable is set, however, it will override all other sources.
In the files that end with .gz when using whereis
:
whereis man
output:
man: /usr/bin/man /usr/bin/X11/man /usr/local/man /usr/share/man /usr/share/man/man1/man.1.gz /usr/share/man/man7/man.7.gz
Example with grep:
whereis grep
output:
grep: /bin/grep /usr/share/man/man1/grep.1.gz
minor update on how to read these gz files:
info /usr/share/man/man1/grep.info.gz
zcat /usr/share/man/man1/grep.1.gz | less
or if it is in the name.number.gz format:
zcat /usr/share/man/man1/grep.1.gz | less
# or more readable
man /usr/share/man/man1/grep.1.gz
They should be under /usr/share/man
.
