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
