basename

basename(1B)					     SunOS/BSD Compatibility Package Commands					      basename(1B)

NAME

       basename - display portions of pathnames

SYNOPSIS

       /usr/ucb/basename string [suffix]

DESCRIPTION

       The  basename  utility deletes any prefix ending in `/' and the suffix, if present in string. It directs the result to the standard output,
       and is normally used inside substitution marks (` `) within shell procedures. The suffix is a string with no special significance  attached
       to any of the characters it contains.

EXAMPLES

       Example 1: Using the basename command.

       This shell procedure invoked with the argument /usr/src/bin/cat.c compiles the named file and moves the output to cat in the current direc-
       tory:

       example% cc $1
       example% mv a.out `basename $1 .c`
