Hi
i wrote script use it as watchdog ( i mean it check another program (pooya) whenever that was killed (closed or crashed) it run another script (pooya_start.sh) to start it,
this script work fine and do the job for me , i need help of an expert to tell me (exact command) how to change this script use Minimum resource ( Cpu & memory) to work?
Code:
while sleep 1
do
  if ps x | grep -v grep | grep -c pooya >/dev/null
  then 
  echo "" 
  else
echo `date` "R" >> /tmp/Check_pooya.log
 /var/bin/pooya_start.sh start &
  fi
done

exit 0

1,( line 3) : i was read in other forum don't grep grep : how could change this to other way ( please wrote exact command for me)

2.( line 5) : is there any better command instead of echo "" use no memory and do nothing ( just wrote this line to do nothing if pooya is run)

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.
