I should stress out that the leading "$" isn't part of the command!

I remember a beginners' intro to unix that prefixed every command with "%" 
in bold (the csh prompt). Some people actually retyped the "%" and got 
frustrated over it! But in that case, there was a space after the prompt 
character so it was more recognisable as such, than $mv. Frankly, I can 
imagine a script that has $sudo and $mv written in it for real and for a 
reason, which is the reason I decided to talk about this rather than not.

Yeah, but if you don't want to do it blindly with trial and error, then 
you gotta use the «ldd» commands on all externals, and then «|grep libGL» 
on that.
