|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl fhiv
|
|
.Ar source target
|
|
.Nm
|
|
.Op Fl fiv
|
|
.Ar source ... directory
|
|
.Sh DESCRIPTION
|
|
In its first form, the
|
|
.Nm
|
|
utility renames 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 or when the
|
|
.Fl h
|
|
flag is specified.
|
|
.Pp
|
|
In its second form,
|
|
.Nm
|
|
moves each file named by a
|
|
.Ar source
|
|
operand to a destination file in the existing directory named by the
|
|
.Ar directory
|
|
operand.
|
|
The destination path for each operand is the pathname produced by the
|
|
concatenation of the last operand, a slash, and the final pathname
|
|
component of the named file.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width flag
|
|
.It Fl f
|
|
Do not prompt for confirmation before overwriting the destination
|
|
path.
|
|
.It Fl h
|
|
Try to rename the source to the target irrespective of whether the
|
|
target may resolve to a directory.
|
|
This option allows atomically replacing a symbolic link to a
|
|
directory.
|
|
.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 ``y'',
|
|
the move is attempted.
|
|
.It Fl v
|
|
Cause
|
|
.Nm
|
|
to be verbose, showing files as they are processed.
|
|
.El
|
|
.Pp
|
|
The last of any
|
|
.Fl f
|
|
or
|
|
.Fl i
|
|
options is the one which affects
|
|
.Nm Ns 's
|
|
behavior.
|
|
.Pp
|
|
It is an error for any of the
|
|
.Ar source
|
|
operands to specify a nonexistent file or directory.
|
|
.Pp
|
|
It is an error for the
|
|
.Ar source
|
|
operand to specify a directory if the
|
|
.Ar target
|
|
exists and is not a directory.
|
|
.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
|
|
.Ar source
|
|
and
|
|
.Ar target
|
|
are on different file systems,
|
|
.Nm
|
|
will remove the destination file, copy the source file to the
|
|
destination, and then remove the source.
|
|
The effect is roughly equivalent to:
|
|
.Bd -literal -offset indent
|
|
rm -f destination_path && \e
|
|
cp -PRp source_file destination_path && \e
|
|
rm -rf source_file

.Sh STANDARDS
|
|
The
|
|
.Nm
|
|
utility is expected to be
|
|
.St -p1003.2
|
|
compatible.
|
|
.Pp
|
|
The
|
|
.Fl h
|
|
and
|
|
.Fl v
|
|
options are extensions to
|
|
.St -p1003.2 .
