I've found an easy way to dig up commands that I can't alltogether remember. While installing an operating system recently, I forgot which command I needed to invoke from the shell which would allow me to configure locales. Using this code I was able to find "tzconfig" on the Debian box I was setting up. *This won't work in most non-*nix environments (eg- DOS). It requires the presence of the "grep" and "ls" commands from within your shell. Obviously, Perl needs to be installed too.
#!/usr/bin/perl -w
use strict; use warnings;

my($cmd) = shift @ARGV || die <<__MORT__;
Nothing to search for.  Invoke this program with the command name or p
+art of
the command name for which you want to search in your \$PATH.

usage: $0 [command to search for in \$PATH]
__MORT__

foreach (split(/:/,$ENV{'PATH'})) {
   print qq[IN "$_"\n], (`ls ${\quotemeta $_}|grep $cmd`||"[none]\n"),
+ "--\n\n"
}
