string compare

Hi,

I am trying to get an ouput of certain fields from a file:

awk '{ print $NF }' portfile

8087
8047
localhost:1117

Now i need to take this output and see if it exists in netstat -a command. How do i check that.

Thanks,
Gundu

Hi Gundu. Try this:

LIST="`awk '{ print $NF }' portfile`"

if netstat -a |egrep -s "$LIST"
then
echo "do this"
else
echo "do that"
fi

Hope this helps.
