I'm working in a Centos 6.6 Docker image. I thought I installed everything to get access to man pages, but apparently not...

$ yum install -y man man-pages man-pages-overrides
[...]
Complete!
$ which man
/usr/bin/man
$ man man
No manual entry for man

What am I missing ?

Regarding questions in comments (thanks for your help everyone):

$ echo $MANPATH
# empty
$ man 1 man
No entry for man in section 1 of the manual
$ man 7 man
No entry for man in section 7 of the manual
$ ll /usr/share/man/man1/
total 8

  • Isn't MANPATH environment variable overriden? Also, try this: man -M /usr/share/man man

  • What are the results of man 1 man and man 7 man, please?

  • Debian has a package called man-db. Of course, CentOS may be set up differently.

  • Do you have the file /usr/share/man/man1/man.1.gz ?

See the comment re: removing tsflags=nodocs from /etc/yum.conf, put there as a purported consequence of base docker image build policy:

I just tested this on a CentOS 6.7 container and it works.

  • Thank you for this; I got man and man pages installed. But for some bizarre reason there's nothing in section 8. Still haven't figured that one out!

If echo $MANPATH is empty you need to set the manpath.

echo "MANPATH=/usr/share/man" >> ~/.bashrc

The login again.

  • I am using Debian 9. $MANPATH is empty and man works.

  • @Debian_yadav+ ditto on CentOS 6.7 (though not docker), and every other implementation of man I've ever used.
