BASENAME(1)                  BSD Reference Manual                  BASENAME(1)

NAME
     basename, dirname - return filename or directory portion of pathname

SYNOPSIS
     basename string [suffix]
     dirname string

DESCRIPTION
     Basename deletes any prefix ending with the last slash `/' character pre-
     sent in string, and a suffix, if given.  The resulting filename is writ-
     ten to the standard output.  If string ends in the slash character, `/',
     or is the same as the suffix argument, a newline is output.  A non-
     existent suffix is ignored.

     Dirname deletes the filename portion, beginning with the last slash `/'
     character to the end of string, and writes the result to the standard
     output.

EXAMPLES
     The following line sets the shell variable FOO to /usr/bin.

           FOO=`dirname /usr/bin/trail`

     Both the basename and dirname exit 0 on success, and >0 if an error oc-
     curs.

SEE ALSO
     csh(1) sh(1)

STANDARDS
     The basename and dirname functions are expected to be POSIX 1003.2 com-
     patible.
