what(1) also works, if you have it.

Linking /bin/ksh to /bin/sh also works (the documentation said it was OK
with this version, so I tried it on one machine about 5 months ago -- no
problems (yet)).  However, ksh does use a startup file ($ENV), which can
slow things down, and may cause unexpected things to happens if the
startup file writes anything to stdout.
