.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. 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 files' 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 user's 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,
|
|
.B chown
|
|
performs the same function as
|
|
.BR chgrp .
|
|
If only a colon is given, or if the entire operand is empty, neither the
|
|
owner nor the group is changed.
|
|
.SH OPTIONS
|
|
.PP
|
|
Change the owner and/or group of each FILE to OWNER and/or GROUP.
|
|
With \fB\-\-reference\fR, change the owner and group of each FILE to those of RFILE.
|
|
.TP
|
|
\fB\-c\fR, \fB\-\-changes\fR
|
|
like verbose but report only when a change is made
|
|
.TP
|
|
\fB\-f\fR, \fB\-\-silent\fR, \fB\-\-quiet\fR
|
|
suppress most error messages
|
|
.TP
|
|
\fB\-v\fR, \fB\-\-verbose\fR
|
|
output a diagnostic for every file processed
|
|
.TP
|
|
\fB\-\-dereference\fR
|
|
affect the referent of each symbolic link (this is
|
|
the default), rather than the symbolic link itself
|
|
.TP
|
|
\fB\-h\fR, \fB\-\-no\-dereference\fR
|
|
affect symbolic links instead of any referenced file
|
|
(useful only on systems that can change the
|
|
ownership of a symlink)
|
|
.TP
|
|
\fB\-\-from\fR=\fI\,CURRENT_OWNER\/\fR:CURRENT_GROUP
|
|
change the ownership of each file only if
|
|
its current owner and/or group match those specified
|
|
here. Either may be omitted, in which case a match
|
|
is not required for the omitted attribute
|
|
.TP

\fB\-\-no\-preserve\-root\fR
|
|
do not treat '/' specially (the default)
|
|
.TP
|
|

|
|
.TP
|
|
\fB\-\-reference\fR=\fI\,RFILE\/\fR
|
|

|
|
.TP
|
|
\fB\-R\fR, \fB\-\-recursive\fR
|
|
operate on files and directories recursively
|
|
.PP
|
|
The following options modify how a hierarchy is traversed when the \fB\-R\fR
|
|

|
|
one takes effect. \fB\-P\fR is the default.
|
|
.TP
|
|

|
|
to a directory, traverse it
|
|
.TP

traverse every symbolic link to a directory
|
|
encountered
|
|
.TP
|
