basename, dirname - deliver portions of pathnames
basename string [ suffix ]
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 (``) within shell procedures.
The suffix is a pattern as defined on the ed(1) manual page.
dirname delivers all but the last level of the pathname in string.
The following example, invoked with the argument /home/sms/personal/mail
sets the environment variable NAME to the filenamed mail and the
environment variable MYMAILPATH to the string /home/sms/personal.
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
mv a.out `basename $1 '\.c'`
language-specific message file (See LANG on environ(5).)
