Actually, which is available on every UNIX system I've ever used...

What you actually want is "$(type -P vncviewer)". Otherwise, if they
have set alias vncviewer='vncviewer -foo' somewhere, type -p returns
nothing, while type -P will return the expected results.

Also, readlink -f isn't portable -- it doesn't work on FreeBSD, at
least. On FreeBSD, you need to use realpath instead.
