Hi,
I am trying to write a script to Count Files in a directory located on a remote server and send an email Notification if it exceeds a limit. The code given below doesnot check the condition and sends the mail everytime irrespective of the condition. I have put this script in the cron. Can anybody please point out the mistake I am making.

#!/bin/ksh
limit=50
file_length= rsh invuk "ssh poller "ls -ltr /var/spool/get | wc -l""
if [ $file_length -ge $limit ]; then
echo "Test mail." |mailx xyz@yahoo.com
fi

Thanks.
