need script for ip address resolution

[mragain]

I have a file with a list of sites like:

.playboy.com
.myspace.com
.etc.com

I want to read each line in the file resolve its ip address and write the ip address that is returned into a another file.

Any help will be greatly appreciate.

I have been looking at nslookup, but I was hoping there was a switch I could pass in that would strip out everything from the response except the servers IP address. The man pages have helped me in getting close to the output I wanted, but still returns more information than I wanted.

thanks

I found the answer in a combination of host and awk:

host -t a google.com | awk '{print($4)}'

appreciate your time and comments.

Would like to replace all instances of "|" (pipe symbol) with a newline in text file so that

http://www.google.com|http://www.slashdot.org|http://www.digg.com...

becomes

http://www.google.com

http://www.slashdot.org

http://www.digg.com

Tried

sed 's/|/\n/' < $input.txt > $output.txt

which didn't work. I'm sure it's my limited knowledge of all things regex that's standing in my way.

Regex school is hard! (but worth it)

TIA!

P.S. I'm trying to convert the output of "Use current pages" in firefox to save the current tabs I have open. I have a tendency to open a bazillion tabs at once and I periodically do a "dump" of what is open just in case firefox crashes. I do use TabMix Plus which is an incredible extension but this way I push my scrtiping knowledge a little further. My goal is to put together a local version of a tagged bookmark file, ala del.icio.us, again learning along the way.

DOH!!!

Sorry!

Filled this out in the wrong place. Guess I need more caffeine.

Again my apologies

You may try something like this:
awk '{gsub(/|/,"\n");print}' $input.txt > $output.txt

Thanks, PHV!

And, again, sorry, vlad!!! I was asleep at the wheel here and placed my new post where a reply belonged. Apparently too much blood in my caffeine system today.
