[SunHELP] Killing processes Part Deux

[David Bishop]

And this doesn't work at all, keeps complaining that -f is an illegal option.
 I normally use ps ax, not ps -ef.  I'm fairly certain that the "cut" part of
my program is working, in that it successfully returns me the list of pids. 
If you notice my second line in the first email was a "echo $a" to double
check that.  Any other ideas?
