ksh script to check if certain process is running
I have to kill the process "test" for a maintenance I do but want the script to check when it comes back up.

I can get what I want when I run this while loop:
while true;do ps -ef | grep test | grep -v grep | sed -e 's/^[ \t]*//';sleep 60;done

but I want the script to do it for me and as soon as the process is found I would like for it to exit. Please advise.

Nevermind I was able to figure it out.

Code:
TESTSTATUS=`ps -ef | grep test | grep -v grep | sed -e 's/^[ \t]*//'`

echo
echo
echo "\033[1;37 \033[1mAs soon as Test processes comes back up it will appear below:\033[0m\n"

until [[ -n $TESTSTATUS ]];do ps -ef | grep test | grep -v grep | sed -e 's/^[ \t]*//';done

zgrep

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.
