This is not very smart, but might do the trick:


if [ -z $1 ]; then
        echo "Needs filename as argument."
        exit 1
elif [ -f "$1" ]; then

while read a;

  echo "$a" | sed -e "s+http://++" -e "s+@.*$++g"

done < "$fname"
* Save this as a shell script of a name you like, e.g.

* Make it executable with chmod +x

* Give your filename as the first argument: filename_that_is_to_big_to_edit_by_hand.txt

and it returns only userass as you wanted
