I just installed CentOS 6 with minimal to install man command ?
[root@LMK-LIN-03 ~]# man
bash: man: command not found
What wrong with Centos? Normally Centos come with man page, how come latest Centos 6 without man page?
[root@LMK-LIN-03 ~]# rpm -q man
package man is not installed
The Linux command “man” is used to display the manual page for other command and also will help you to explain the functions for the commands that commonly used. The term “man” is short for manual. To install “man”, simply run this command :
[root@LMK-LIN-03 ~]# yum install man -y
After installed, you should be able to access man command.
