What is the path or “man” command ?

[root@centos62 ~]# which man
/usr/bin/man

Example of “man” command that will display chown manual page :

[root@centos62 ~]# man chown
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
