NAME

chown, chgrp − change file owner or group

SYNOPSIS

chown owner file ... 

chgrp group file ... 

DESCRIPTION

Chown changes the owner of the files to owner. The owner may be either a decimal user ID or a login name found in the password file. 

Chgrp changes the group ID of the files to group. The group may be either a decimal group ID or a group name found in the group file. 

In order to change the owner or group, you must own the file or be the super-user.  If either command is invoked by other than the super-user, the set-user-ID and set-group-ID bits of the file mode, 04000 and 02000 respectively, will be cleared.
