Besides the fact that this is horribly off-topic, the question doesn't really make sense neither ;)

Linux doesn't have a "minimal set of tools" that should be on each system. You -as r00t- may delete whatever you see fit. Apparantly, your sysadmin did indeed delete the binary, for there seem to be manual pages around. I've checked two systems (Slack and Debian) and the binary resides in /usr/bin/ on both machines I've checked.

So, either install it (tarball/.deb/.rpm/.whatever), or -to make this a lil' more on topic- create a script that does the same, using Convert::UU :)

Update: Edited (<strike>) to fit the completely altered root node ...
