NAME
 basename, dirname — return filename or directory portion of pathname
DESCRIPTION
 basename deletes any prefix ending with the last slash ‘
/' character present in 
string, and a 
suffix, if given. The resulting filename is written to the standard 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.
 
EXIT STATUS
 Both the basename and dirname utilities exit 0 on success, and >0 if an error occurs.
EXAMPLES
 The following line sets the shell variable 
FOO to 
/usr/bin.
FOO=`dirname /usr/bin/trail`
 
STANDARDS
 The basename and dirname utilities conform to IEEE Std 1003.2-1992 (“POSIX.2”).
