   In ksh, `whence' is a bit equivalent to `which' (`type' in ksh
is an alias to `whence -v').

   From the AT&T ksh manual:

       whence [ -afpv ] name ...
              For each name, indicate how it would be interpreted
              if used as a command name.
              The  -v option produces a more verbose report.  The
              -f options skips the search for functions.  The  -p
              option  does a path search for name even if name is
              an alias, a function, or a reserved word.   The  -a
              option  is  similar to the -v option but causes all
              interpretations of the given name to be reported.

   Which would yield the following behavior:

$ whence pwd
pwd
$ whence -f pwd
pwd
$ whence -p pwd
/bin/pwd
$ whence -v pwd
pwd is a shell builtin
$ whence -a pwd
pwd is a shell builtin
pwd is a tracked alias for /bin/pwd
