Good to know.

Of course, if you use lots of platforms other than Ubuntu, the
8-line version is easy to drop in on the fly.  You can run it on
other Linuxes or the BSDs.  You can run it on Windows boxes with
Cygwin, or even Windows with ActiveState Perl (with a wee bit of
tweaking).  It's short enough to type by hand if you don't have any
other way to get it onto your target system.

Oops, I'm raving.  Please excuse...
