Question

I am trying to write a script that when triggered by an ip address it will run the following
export DAVIDCOUNT=`(fgrep -ce 140.147.146.146 /export/home/ipconnect.txt) >> /local/cron/test_listen_out`;
I think this is my problem line.
What I like this line to do is when it sees the 140.147.146.146 ip address, it goes to the ipconnect.txt file, finds the line that corresponds to the ip address and print the whole line of text that has 140.147.146.146.
Is this possible?
