Modification in shell script
Hello Team,

I have prepared script which will check for listening message for ports 1199,1200 and 1201. I need modifcation in script in such a way that if port 1200 is not listening then it should message rmi port 1200 is not listening. Smap for port 1199 and 1201.
kindly guide me to acheive this solution

Code:
#!/usr/bin/ksh

status=`netstat -na | grep 1200 | grep -i listen |sed -n '1p'| awk {'print $7'}`

status1=`netstat -na | grep 1201 | grep -i listen |sed -n '1p'| awk {'print $7'}`

status2=`netstat -na | grep 1199 | grep -i listen |sed -n '1p'| awk {'print $7'}`

for s1 in $status $status1 $status2

if [ $s1 = "LISTEN" ];

then

echo "RMi Server is running fine on server `hostname` @ `date`"

else

echo "RMI Server is not running fine on server `hostname` @`date`" >>/opt/app/rmiserver.txt

fi

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.
