.SH Syntax
.B mv
[\fB\-i\fR] [\fB\-f\fR\|] [\fB\-\fR] \fIfile1 file2\fR
.PP
.B mv
[\fB\-i\fR] [\fB\-f\fR\|] [\fB\-\fR] \fIfile... directory\fR
.SH Description
.NXR "mv command" 
.NXR "file" "moving"
.NXR "file" "renaming"
The
.PN mv
command
moves (changes the name of)
.I file1
to
.IR file2 .
.PP
If
.I file2
already exists, it is removed before
.I file1
is moved.  If
.I file2
has a mode which forbids writing,
.PN mv
prints the mode 
and reads the standard input to obtain a line.  If the line begins with
.B y,
the move takes place.  If it does not,
.PN mv
exits.
For further information, see 
.MS chmod 2 .
.PP
In the second form, one or more
.I files
(plain files or directories) are moved to the
.I directory
with their original file-names.
.PP
The
.PN mv
command refuses to move a file onto itself.
.SH Options
.IP \fB\-\fR 20
Interprets all following arguments as file names to allow file names starting with
a minus.  
.IP \fB\-f\fR 20
Force. This option overrides any mode restrictions or the
\-i switch.
.IP \fB\-i\fR 20
Interactive mode.  If a move is to supersede an
existing file, the system prompts youw with the name of the file
followed by a question mark.  If you type a string that begins
with y, the move occurs.  If you type any other response, the move does
not occur.
.SH Restrictions
If
.I file1
and
.I file2
lie on different file systems,
.PN mv
must copy the file and delete the original.
In this case the owner name becomes that of the copying process and any
linking relationship with other files is lost.
