I'm working in a tcsh environment, and the builtin "killall" just isn't doing it for me.

So ... I decided to try and write an alias (using in-line perl) that would do what I want: 
alias ka 'ps -ef|&perl -n -e '"'"'END{@a&&kill(9,@a)}($a=(split())[1])
+!=$$&&/\!:1/&&kill(2,$a)&&push(@a,$a)&&print'"'"''

The problem is, if I use this alias without specifying any arguments I get a "bad ! arg selector" message (because of the "!:1" reference). Is there any way to trap the error message output in the code -- or make sure that the code never gets to the point where it needs to worry about it?

Also, it'd be great if I could get away from using my @a and $a temporary variables, but that's beyond the real scope of my question. :^)

Thanks a bunch!
