There are some commands that you could type at the CLI that will cause
the system to lock up and or crash. Some could involve a !. One
doesn't come to mind, but the most famous one I can think of is
"forkbomb".
:(){:|:&};: this command will tell your system to execute a huge
number of processes until the system freezes.
So yes there is something you can type that will cause a system to go
crazy. However that has nothing to do with getting access to the
system in the first place.

the quick obvious take down of the statement this person made is to
ask "if that was true why does LAMP power so much of the internet?".

If Linux was so weak it would not have the market share that it does.
