.SH SYNOPSIS
|

.B chown

[\-\-silent] [\-\-quiet] [\-\-verbose] [user][:.][group] file...

.SH DESCRIPTION
|
|
This manual page
|
|
documents the GNU version of
|
|
.BR chown .
|
|
.B 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,
|
|
.B chown
|
|
performs the same function as
|
|
.BR chgrp .
|
|

|
|
The long-named options can be introduced with `+' as well as `\-\-',
|
|
for compatibility with previous releases. Eventually support for `+'
|
|
will be removed, because it is incompatible with the POSIX.2 standard.
