multiple command in ssh giving error

Hi

I have prepared a script which will login to each server and search for a keyword.
I want output on same machine from where m running script.

When i try to run command on any machine.. It works well.

w=$(grep -irH "keyword.com" /home/*/public_html/*);if [ $? -eq 0 ];then echo -e "\n $HOSTNAME";echo $(grep -irH "keyword.com" /home/*/public_html/* | cut -d: -f1 | uniq | awk '{for (i=1;i<=NF;i++) printf "%s \n",$i}');fi

but its not working in script with ssh
its gives below error:
script.sh: line 5: syntax error near unexpected token `('

Script is:

#!/bin/ksh
echo -e "Script to check and list if keyword is being used by any server \n" > /tmp/test.txt
for f in `cat /root/sync_script/serverlist1.txt`
do
ssh $f.exam5.com 'w=$(grep -irH "keyword.com" /home/*/public_html/*);if [ $? -eq 0 ];then echo -e "\n $HOSTNAME";echo $(grep -irH "keyword.com" /home/*/public_html/* | cut -d: -f1 | uniq | awk '{for (i=1;i<=NF;i++) printf "%s \n",$i}');fi' >> /tmp/test.txt
done

Please respond ASAP.

Thanks & Regards,
Monika

Please don't cross-post, it is against the LQ rules

Continue in this thread: multiple command in ssh not working for me.

Don't demand an immediate answer, we are all volunteers here.....

Reported.

Welcome to LQ. I hope you get as much out of it as I have.

Although I would have added a "please" to the "we are all volunteers here" part, druuna is right on both counts. So, please read or re-read those rules, & again welcome.

Probably, the error occurs due to bolded apostrophes (too much of them - You should have 2 instead of 4). Try to rewrite it, so that You use proper open-close apostrophes scheme.
