I am trying to create a script which removes a list of servers from a text file for a hosts file ???

I have tried all kinds of combinations with if statements but cant seem to find anything that works ???

all i want to do is remove a list of servers in one text from another text file.
Sounds easy but any help will be appreciated.

Post your existing code and I can probably help you.

This should give a start. If you want to test this out. If it works to your liking then add another line at the end.... mv -f hosts.temp hosts

for filename in remove.hosts
do
cat $filename | \
while read line
do
sed -e 's/'"$line"'/ /g' hosts > host.temp
done
done

why use cat when the while loop can take in input?

while read line
do
 ....
done < filename

Good question. Can just specify filename and remove the other associated lines.

I probably would have done a reverse grep. But sed is good as well.
