create checkscript first, scp it over to the remote servers and run ... all output from all remote script runs will be in local /dir/log ...

checkscript <-- to run at remote servers
Code:
#! /bin/ksh
hostname
echo "=============="
CLECount=$(ps -ef |grep ELINKDEV |grep CLE |grep -v grep| wc -l)
PurgeDataCount=$(ps -ef |grep ELINKDEV |grep PurgeData |grep -v grep| wc -l)
if [[ "$CLECOUNT" = "3" && "$PurgeDataCount" = "1" ]]
then
echo "CLE Components................Running"
else
echo "CLE Components................Not Running"
fi
echo
exit 0

runscript <-- run locally on command line
Code:
#! /bin/ksh
LOG=/dir/log
SCRIPT=checkscript

for HOST in host1 host2 host3 host4
do
    scp -p $SCRIPT user@${HOST}:/tmp/${SCRIPT}
    ssh -n user@${HOST} "/tmp/${SCRIPT} && rm /tmp/${SCRIPT}"
done > $LOG 2>&1

exit 0

local /dir/log entries
Code:
host1
==============
CLE Components................Running

host2
==============
CLE Components................Running

host3
==============
CLE Components................Running

host4
==============
CLE Components................Running

Thanks Ice Age.

See I have different code snippets in my script file which i need to run at different servers

For eg. Below is my script file

Code:
 
# Run this code in Server 1
 
CLECount=$(ps -ef |grep ELINKDEV |grep CLE |grep -v grep| wc -l)
PurgeDataCount=$(ps -ef |grep ELINKDEV |grep PurgeData |grep -v grep| wc -l)
if [[ "$CLECOUNT" = "3" && "$PurgeDataCount" = "1" ]]
then
echo "CLE Components................Running"
else
echo "CLE Components................Not Running"
fi
echo
exit 0

 
# Run this on Server 2
Count=$(ps -ef |grep ELINKDEV |grep engine |grep -v grep| wc -l)
if [ "$Count" = "0" ];
then
            echo "ALL Components................Stopped">>OutputResult.txt
            else
            echo "Components................Running">>OutputResult.txt
fi
 
#Run this on server 3
 
Count=$(ps -ef |grep ELINKDEV |grep Serverengine |grep -v grep| wc -l)
if [ "$Count" = "0" ];
then
            echo "ALL Server Components................Stopped">>OutputResult.txt
            else
            echo "Server Components................Running">>OutputResult.txt
fi


As you suggested above It will run to the host 1, host 2. host3 all the commnds but i want to run specfic command to specific server.

I am really looking forward towards you as It seems am very close to get solution from you.

just create all those scripts separately -- remove all the output redirections as per earlier post -- and list them in a file with the hostnames (see sample below) ... then run the scp-ssh-log routine as suggested ...

hostscript.txt
Code:
host1:clescript
host2:compscript
host3:svrsrcipt

runscript
Code:
#! /bin/ksh
HSFILE=/dir/hostscript.txt
LOG=/dir/log

for HOST in $(awk -F":" '{print $1}' $HSFILE)
do
    SCRIPT=$(awk -F":" "\$2 ~ /$HOST/ {print \$2}" $HSFILE)
    scp -p $SCRIPT user@${HOST}:/tmp/${SCRIPT}
    ssh user@${HOST} "/tmp/${SCRIPT} && rm /tmp/${SCRIPT}"
done > ${LOG} 2>&1

exit 0

Thansk ICE Age,

Actually for maintaince purpose, we dont want to keep multiple scripts file to invoke for differnt servers
In HostScript.txt, I have to invoke single script file on multiple hosts which will be having different logic for differnt server.

Is it the way to pass the variable which contains the host name to the main script(assume host name) and there I will put logic to run only those parts of scripts for particular host name.
