Data printing a line from a file

I think that the former thread is not correct.
What I am trying to do is when the script is triggered by
an ip address, it goes to a file called ipconnect.txt and
print the row that has the corresponding ip address in it.
The data in ipconnect is a list of ip address followed by a
tab and then the owner's ip address.
This is the entire script and I think that the netstat is
what need to be looked at.

export HOUR=`/usr/bin/date +%H`
export MINUTE=`/usr/bin/date +%M`
export REMOTECOUNT=`ps -ef | grep LOCAL=NO | wc -l`;
if [ $REMOTECOUNT -ne 1 ]
then
export REMOTER=`expr ${REMOTECOUNT} - 1`
print $REMOTER "=REMOTE CONNECTIONS" > /cron/test_listen_out;
netstat -an | grep "50.1521" | cut -c22-42 | egrep -v /cron/stars >> /cron/test_listen_out;
export DAVIDCOUNT=`fgrep -ce 140.147.146.146 /ipconnect.txt`;
fgrep 140.147.146.146 >> /cron/test_listen_out;
if [ $DAVIDCOUNT -ne 0 ]
then
print "David Williamson" >> /cron/test_listen_out;
fi
...
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 is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci- fied, 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 zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep zgrep string files for csh: (setenv GREP fgrep; zgrep string files) AUTHOR
