CentOS 6.2 is an older version of CentOS and has reached its End of Life (EOL) on November 30, 2020. It is strongly recommended that you upgrade to a newer version, such as CentOS 7 or 8, as they receive security updates and support.
[root@centos62 ~]# man chown -bash: man: command not found
However, if you still need to install the “man” command on CentOS 6.2, you can follow these steps:
Step 1: Update the Package List
First, open a terminal window and run the following command to update the package list:
sudo yum update
This command fetches the latest package information from the configured repositories and updates the local package list.
Step 2: Install the “man” Command
After updating the package list, install the “man” command and the required packages using the following command:
sudo yum install -y man man-pages
This command installs the “man” package and the man-pages package, which contains the manual pages for Linux commands and functions.

Step 3: Verify the Installation
To verify that the “man” command has been successfully installed, run the following command:
man chown
This command displays the manual page for the “chown” command.
CHOWN(1) User Commands CHOWN(1)
NAME
chown - change file owner and group
SYNOPSIS
chown [OPTION]... [OWNER][:[GROUP]] FILE...
chown [OPTION]... --reference=RFILE FILE...
DESCRIPTION
This manual page documents the GNU version of chown. chown changes the user and/or
group ownership of each given file. If only an owner (a user name or numeric user
ID) is given, that user is made the owner of each given file, and the filesâ group
is not changed. If the owner is followed by a colon and a group name (or numeric
group ID), with no spaces between them, the group ownership of the files is changed
as well. If a colon but no group name follows the user name, that user is made the
owner of the files and the group of the files is changed to that userâs login
group. If the colon and group are given, but the owner is omitted, only the group
of the files is changed; in this case, chown performs the same function as chgrp.
If only a colon is given, or if the entire operand is empty, neither the owner nor
the group is changed.
OPTIONS
Change the owner and/or group of each FILE to OWNER and/or GROUP. With --refer-
ence, change the owner and group of each FILE to those of RFILE.
-c, --changes
like verbose but report only when a change is made
If you see the manual page, the installation was successful.
Conclusion
You have now successfully installed the “man” command on your CentOS 6.2 system. However, it is important to note that CentOS 6.2 is no longer supported, and you should consider upgrading to a newer version to ensure the security and stability of your system.
