Script Help

[eeezeepeezee]

im having problems with this:

i have a file which contains some data about internet hits log:

123.123.123 Mon Feb 23 2008
123.123.123 Mon Feb 23 2008
"
"

i can prompt the user to type a time period so i can store it in a vaiable so it can compare it to the file. then it can increment the number of hits a certain file has in the given time period. but i cant seem to compare the IP addresses and output the number of unique IPs.

Heres part of my script:

echo "Enter Period "
read PERIOD

grep "$PERIOD" *.hits | wc -l

i have also tried using awk to solve the same problem but im pretty stuck

any help!?!

Thanks all
