[NAME]chown \- change file owner and group[DESCRIPTION]This manual pagedocuments the GNU version of.BR chown ..B chownchanges the user and/or group ownership of each given file, accordingto its first non-option argument, which is interpreted as follows.  Ifonly a user name (or numeric user ID) is given, that user is made theowner of each given file, and the files' group is not changed.  If theuser name is followed by a colon or dot and a group name (or numeric group ID),with no spaces between them, the group ownership of the files ischanged as well.  If a colon or dot but no group name follows the user name,that user is made the owner of the files and the group of the files ischanged to that user's login group.  If the colon or dot and group are given,but the user name is omitted, only the group of the files is changed;in this case,.B chownperforms the same function as.BR chgrp ..SH OPTIONS
