basename string [ suffix ]
dirname string

basename deletes any prefix ending in / (forward slash) and the suffix (if present in string) from string, and prints the result on the standard output.

Example A.6.
1    basename /usr/local/bin

Explanation

  1. Strips off the prefix /usr/local/ and displays bin.

  2. Assigns just the name of the script, $0, to the variable scriptname.
