Old 12-16-2010
It's KSH..AIX, but I was actually able to figure something out.

Heres what I want to do.

Code:
 
proc1=$(ps -ef | grep proc1| awk '{ print $2}')                      
proc2=$(ps -ef | grep proc2| awk '{ print $2}') 
while proc1 or proc2 is not running
do
script
done

I just need help setting up the part of the logic for "or" and "if it isn't running..would it be something like this.

Code:
while [$proc1 -lt 0 -o $proc2 -lt 0 ]
do
script
done

zegrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  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 the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
