String manipulation for PID

Hi, I'm having trouble figuring out something for a script I'm writing. Where I work, we have 3 process that run a device, and they occasionally need to be killed. Everyone is doing this manually, looking up the PIDs one at a time and then typing the kill statements and PIDs manually. I'd like to take away the potential for user error there, and I'm setting up a script to do that. So what I've got is basically :

ps -awx | fgrep "proc_one
proc_two
proc_three"


and this gives me a list of 4 processes -- the 3 I want to kill and the fgrep process also (shows up something like fgrep?proc_one?proc_two?proc_three?). what I need to do is pull the PIDs from the 3 that I want to kill but not the fgrep one. I'm not sure what length the PIDs are going to be, and I'm not any good with awk or sed anyway. can anyone help me out with this one?

Thanks

NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
gzgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci- fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep gzgrep string files for csh: (setenv GREP fgrep; gzgrep string files) AUTHOR
