script - ignore case

[Ravinder Singh Gill]

while I am doing the following grep I want it to ignore the case, I do not want to change the case so that they are all lowercase etc. What options/command do I need so that it ignores the case?

while read fakeuser
do
grep $fakeuser passgvts | awk -F":" '{print $1}' >> queryusers
done < testnotokusers
cat queryusers | sort | uniq > newfile

Use as,

while read fakeuser
do
grep -i "${fakeuser}" passgvts | awk -F":" '{print $1}' >> queryusers
done < testnotokusers

sort queryusers | uniq > newfile
