Note: This applies to Centos 7. If you are looking for a Debian answer, see this question. Those answers will not be duplicated here.

After an install of centos 7, I can't access man pages :

# man ls
-bash: man: command not found

I tried to install it via yum

# yum install man-pages
... ok

But again:

# man ls
-bash: man: command not found

    This is extremely weird, as man(1) is a very fundamental piece of the system. You could try to reinstall, i.e., go yum reinstall /usr/bin/man. – vonbrand Dec 31 '15 at 23:01

In order to use the man command, you must also install the man package before or after the man-pages one

# yum install man-pages
... ok
# yum install man
... ok

Now man is installed

# man ls

      ls - list directory contents

      ls [OPTION]... [FILE]...

      List information about the FILEs (the current directory by default).  Sort entries alphabetically if none of -cftuvSUX nor --sort.

      Mandatory arguments to long options are mandatory for short options too. ...

    Apparently this doesn't work on centOS inside a docker container. I know I've gotten this to work in a centOS VM, but unsure why its not working in the container. – jersey bean Jan 10 '18 at 21:07

    Ok, I just found my answer. Docker centos images are prebuild with tsflags=nodocs set in /etc/yum.conf. See hub.docker.com/_/centos – jersey bean Jan 10 '18 at 22:26
  • Yes you're right! +1 for the complement. Thanks! – Rémi B. Jan 11 '18 at 13:34

The syntax on CentOS 7:

# yum install man-pages man-db man

The syntax on CentOS 6:

$ sudo yum install man man-pages



I had the same problem in my docker container and solved it by commenting out the tsflags=nodocs in /etc/yum.conf file, then I removed the man-pages and man-db and reinstall them again. It works fine this way.

$ vi /etc/yum.conf

Search for tsflags into the file and add a comment (#) in front of it:


Now remove the man-db and the man-pages if it's already installed on your system:

$ yum remove man-pages man-db

Then install them again:

$ yum install man-pages man-db
