.SH NAME
|
|
.PP
|
|
\fBbasename\fR, \fBdirname\fR
|
|
\- return filename or directory portion of pathname
|
|
.SH SYNOPSIS
|
|
.PP
|
|
\fBbasename\fR \fIstring\fR [\fI.suffix\fR]
|
|
.sp 1
|
|
\fBdirname\fR \fIpath\fR
|
|
.SH DESCRIPTION
|
|
.PP
|
|
\fBBasename\fR
|
|
deletes any prefix ending with the last slash \/ or colon :
|
|
character present in \fIstring\fR, and a \fIsuffix\fR,
|
|
if given. The resulting filename is written to the
|
|
standard output. Any trailing slash \/ or colon : characters
|
|
in \fIstring\fR will be removed. A non-existent suffix is
|
|
ignored.
|
|
.PP
|
|
\fBDirname\fR deletes the filename portion, beginning
|
|
with the last slash \/ or colon : character to the end
|
|
of \fIstring\fR, and writes the result to the standard
|
|
output.
|
|
.SH EXAMPLES
|
|
.PP
|
|
The following line sets the shell variable \fBFOO\fR
|
|
to \fI/usr/bin\fR.
|
|
.PP
|
|
\fBFOO=`dirname /usr/bin/trail`\fR
|
|
.PP
|
|
Both the \fBbasename\fR and \fBdirname\fR
|
|
exit 0 on success, and >0 if an error occurs.
|
|
.SH NOTES
|
|
.PP
|
|
Because these programs use \fBbasename\fR(3) and
|
|
\fBdirname\fR(3) respectively, there is a preference
|
|
on ':' as a deliminator. Additionally, if a ':' is
|
|
used anywhere in the pathname, it will be considered
|
|
the deliminator.

|
|
.SH STANDARDS
|
|
.PP
|
|
The \fBbasename\fR and \fBdirname\fR functions are
|
|
expected to be POSIX 1003.2 compatible.
