NAME
basename - strip filename affixes

SYNOPSIS
basename string [ suffix ]

DESCRIPTION
Basename deletes any prefix ending in ‘/’ and the suffix, if
present in string, from string, and prints the result on the
standard output. It is normally used inside substitution marks ‘ ‘
in shell procedures.

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
directory:

cc $1
mv a.out ‘basename $1 .c‘
