I "grew up" on Solaris (well, SunOS and H/UX and Mt. Xinu BSD on Vaxen before 
Solaris). Even though 90%+ of my admin work in recent years has been on Linux, 
I still don't use killall...and the rare times that I encounter it, I check the 
man page carefully.

=> behavior of killall on linux: kill all processes matching a specific name.
=> behavior of killall on solaris: kill all processes (and ignore argv[1])

Yeah, that's gonna hurt.



Here's another one...imagine the following sequence of commands run as root:

	someserver# command1 &
	someserver# command2 &
	someserver# command3 &
	someserver# kill %3
	someserver# kill %2
	someserver# kill  1

Ooops! Forgot that little tiny "%"...you've just killed "init". Actually, the 
last few times I played around with this, the init() processes takes more than
just "kill" w/o specifying the signal to kill it. This was not always the case. :(
