.SH NAME
rm, rmdir  \- remove (unlink) files
.SH SYNOPSIS
.B rm
[
.B \-fri
] file ...
.PP
.B rmdir
dir ...
.PP
.SH DESCRIPTION
.I Rm
removes the entries for one or more
files
from a directory.
If an entry was the last link to the file, the file
is destroyed.
Removal of a file requires write permission in its directory,
but neither read nor write permission on the file itself.
.PP
If a file has no write permission
and the standard input is a terminal,
its permissions are printed and a line is read from
the standard input.
If that line begins with `y' the file is deleted,
otherwise the file remains.
No questions are asked
when the
.B \-f
(force) option is given.
.PP
If a designated file is a directory,
an error comment is printed unless the optional
argument
.B \-r
has been used.
In that case,
.I rm
recursively deletes the
entire contents of the specified directory,
and the directory itself.
.PP
If the
.B \-i
(interactive) option is in effect,
.I rm
asks whether to delete each file,
and, under
.BR \-r ,
whether to examine each directory.
.PP
.I Rmdir
removes entries for the named directories,
which must be empty.

.SH DIAGNOSTICS
Generally self-explanatory.
It is forbidden to remove the file `..' merely to avoid the
antisocial consequences of inadvertently doing something like
`rm \-r .*'.
