|
|
.Sh SYNOPSIS
|
|
.Nm mv
|
|
.Op Fl fiv
|
|
.Ar source target
|
|
.Nm mv
|
|
.Op Fl fiv
|
|
.Ar source ... directory
|
|
.Sh DESCRIPTION
|
|
In its first form, the
|
|
.Nm
|
|
utility moves the file named by the
|
|
.Ar source
|
|
operand to the destination path named by the
|
|
.Ar target
|
|
operand.
|
|
This form is assumed when the last operand does not name an already
|
|
existing directory.
|
|
.Pp
|
|
In its second form,
|
|
.Nm
|
|
moves each file named by a
|
|
.Ar source
|
|
operand to the destination specified by the
|
|
.Ar directory
|
|
operand.
|
|
It is an error if the
|
|
.Ar directory
|
|
does not exist.
|
|
The destination path for each
|
|
.Ar source
|
|
operand is the pathname produced by the concatenation of the
|
|
.Ar directory
|
|
operand, a slash, and the final pathname component of the named file.
|
|
.Pp
|
|
In both forms, a
|
|
.Ar source
|
|
operand is skipped with an error message
|
|
when the respective destination path is a non-empty directory,
|
|
or when the source is a non-directory file but the destination path
|
|
is a directory, or vice versa.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl f
|
|
Do not prompt for confirmation before overwriting the destination
|
|
path.
|
|
The
|
|
.Fl f
|
|
option overrides any previous
|
|
.Fl i
|
|
options.
|
|
.It Fl i
|
|
Causes
|
|
.Nm
|
|
to write a prompt to standard error before moving a file that would
|
|
overwrite an existing file.
|
|
If the response from the standard input begins with the character
|
|
.Dq y ,
|
|
the move is attempted.
|
|
The
|
|
.Fl i
|
|
option overrides any previous
|
|
.Fl f
|
|
options.
|
|
.It Fl v
|
|
Display the source and destination after each move.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility moves symbolic links, not the files referenced by the links.
|
|
.Pp
|
|
If the destination path does not have a mode which permits writing,
|
|
.Nm
|
|
prompts the user for confirmation as specified for the
|
|
.Fl i
|
|
option.
|
|
.Pp
|
|
Should the
|
|
.Xr rename 2
|
|
call fail because the source and destination are on different file systems,
|
|
.Nm
|
|
will use
|
|
.Xr cp 1
|
|
and
|
|
.Xr rm 1
|
|
to accomplish the move.
|
|
The effect is equivalent to:
|
|
.Bd -literal -offset indent
|
|
$ rm -df -- destination_path && \e
|
|
cp -PRp -- source destination_path && \e
|
|
rm -rf -- source

.Sh EXIT STATUS
|
|
.Ex -std mv
|
|
.Sh EXAMPLES
|
|
Rename file
|
|
.Pa foo
|
|
to
|
|
.Pa bar ,
|
|
overwriting
|
|
.Pa bar
|
|
if it already exists:
|
|
.Pp
|
|
.Dl $ mv -f foo bar
|
|
.Pp
|
|
Either of these commands will rename the file
|
|
.Pa -f
|
|
to
|
|
.Pa bar ,
|
|
prompting for confirmation if
|
|
.Pa bar
|
|
already exists:
|
|
.Bd -literal -offset indent
|
|
$ mv -i -- -f bar
|
|
$ mv -i ./-f bar

|
|
.Sh STANDARDS
|
|
The
|
|
.Nm
|
|
utility is compliant with the
|
|
.St -p1003.1-2008
|
|
specification.
|
|
.Pp
|
|
The flag
|
|
.Op Fl v
|
|
is an extension to that specification.
|
|
.Sh HISTORY
|
|
A
|
|
.Nm
|
|
command appeared in
|
|
.At v1 .
|
|
.Sh CAVEATS
|
|
In the second synopsis form, incompatible file types in
|
|
.Ar source
|
|
and
|
|
.Ar directory
|
|
cause partial moves.
|
|
For example, if
|
|
.Pa f
|
|
and
|
|
.Pa g
|
|
are non-directory files and
|
|
.Pa d
|
|
and
|
|
.Pa d/f
|
|
are directories, the command
|
|
.Pp
|
|
.Dl $ mv f g d
|
|
.Pp
|
|
will print an error message, leave
|
|
.Pa f
|
|
where it is, move
|
|
.Pa g
|
|
to
|
|
.Pa d/g
|
|
and return a non-zero exit status.
