Bash script to edit text file


I have a text file that is too big to edit by hand and I want to create a simple little script that deletes part of the entry and leaves the rest.

For example, every line has something like this:

Code:
http://user:pass@whatever.whatever.com/
I want to only have
Code:
user:pass
Can anyone help?

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

Code:
#!/bin/sh

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

while read a;
do

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

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

* Make it executable with chmod +x url-extract.sh

* Give your filename as the first argument:
url-extract.sh filename_that_is_to_big_to_edit_by_hand.txt

and it returns only userass as you wanted
