SYNOPSIS
chown [-Rcfv] [--recursive] [--changes] [--help] [--version] [--silent] [--quiet] [--verbose] [user][:.][group] file...

DESCRIPTION
This documentation is no longer being maintained and may be inaccurate or incomplete. The Texinfo documentation is now the authoritative source.

This manual page documents the GNU version of chown. chown changes the user and/or group ownership of each given file, according to its first non-option argument, which is interpreted as follows. If only a user name (or numeric user ID) is given, that user is made the owner of each given file, and the files' group is not changed. If the user 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 is changed 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 is changed 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, chown performs the same function as chgrp.
