.SH SYNOPSIS
|
|
|
|
.LP

|
|
\fBrmdir\fP \fB[\fP\fB-p\fP\fB]\fP \fIdir\fP\fB...\fP
|
|

|
.SH DESCRIPTION
|
|
|
|
.LP
|
|
|
|
The \fIrmdir\fP utility shall remove the directory entry specified
|
|
|
|
by each \fIdir\fP operand.
|
|
|
|
.LP
|
|
|
|
For each \fIdir\fP operand, the \fIrmdir\fP utility shall perform
|
|
|
|
actions equivalent to the \fIrmdir\fP() function called with the \fIdir\fP
|
|
|
|
operand as its only argument.
|
|
|
|
.LP
|
|
|
|
Directories shall be processed in the order specified. If a directory
|
|
|
|
and a subdirectory of that directory are specified in a
|
|
|
|
single invocation of the \fIrmdir\fP utility, the application shall
|
|
|
|
specify the subdirectory before the parent directory so that
|
|
|
|
the parent directory will be empty when the \fIrmdir\fP utility tries
|
|
|
|
to remove it.
|
|
|
|
.SH OPTIONS
|
|
|
|
.LP
|
|
|
|
The \fIrmdir\fP utility shall conform to the Base Definitions volume
|
|
|
|
of IEEE\ Std\ 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
|
|
|
|
.LP

|
|
The following option shall be supported:
|
|
|
|
.TP 7
|
|
|
|
\fB-p\fP
|
|
|
|
Remove all directories in a pathname. For each \fIdir\fP operand:
|
|
|
|
.RS
|
|
|
|
.IP " 1." 4
|
|
|
|
The directory entry it names shall be removed.
|
|
|
|
.LP
|
|
|
|
.IP " 2." 4
|
|
|
|
If the \fIdir\fP operand includes more than one pathname component,
|
|
|
|
effects equivalent to the following command shall
|
|
|
|
occur:
|
|
|

.SH APPLICATION USAGE
|
|
|
|
.LP
|
|
|
|
The definition of an empty directory is one that contains, at most,
|
|
|
|
directory entries for dot and dot-dot.
|
|
|
|
.SH EXAMPLES
|
|
|
|
.LP
|
|
|
|
If a directory \fBa\fP in the current directory is empty except it
|
|
|
|
contains a directory \fBb\fP and \fBa/b\fP is empty except
|
|
|
|
it contains a directory \fBc\fP:
|
|
|
|

|
|
|

|
|
|

.RE
|

.LP
|
|
|
|
removes all three directories.
|
|
|
|
.SH RATIONALE
|
|
|
|
.LP
|
|
|
|
On historical System V systems, the \fB-p\fP option also caused a
|
|
|
|
message to be written to the standard output. The message
|
|
|
|
indicated whether the whole path was removed or whether part of the
|
|
|
|
path remained for some reason. The STDERR section requires this
|
|
|
|
diagnostic when the entire path specified by a \fIdir\fP operand is
|
|
|
|
not removed, but does not allow the status message reporting
|
|
|
|
success to be written as a diagnostic.
|
|
|
|
.LP
|
|
|
|
The \fIrmdir\fP utility on System V also included a \fB-s\fP option
|
|
|
|
that suppressed the informational message output by the
|
|
|
|
\fB-p\fP option. This option has been omitted because the informational
|
|
|
|
message is not specified by this volume of
|
|
|
|
IEEE\ Std\ 1003.1-2001.
