Hashing URLs

So, I am writing a script that will read output from Bulk Extractor (which gathers data based on regular expressions). My script then reads the column that has the URL found, hashes it with MD5, then outputs the URL and hash to a file.

Where I am stuck on is that I want to read the bulk extractor output, line by line. I want to take the 2nd column, and add that as a variable named "url". I then want to take that URL, and hash it with MD5 and assign that to the variable "hash".

I then want to output $url and $hash to an output file, both on the same line.

But, when I use :

Code:

while read line
	do
		url=`awk '{print $2}'`
		hash=`awk '{print $2}' | md5sum`
		echo $url
	done < $iname/url.txt

to walk through the input file, line by line, it globs them all together. $url has EVERY URL, and $hash is a hash value of ALL the URLs.

I know this snippet of code works - I've used it before. So, what is going on?

Here is a snippet of the input :

NAME

       script - Makes a transcript of terminal session

SYNOPSIS

       script [-a] [file]

       The script command makes a transcript of everything printed on your terminal.

OPTIONS

       Appends the transcript to file rather than writing it to file.

OPERANDS

       The name of an output file that will contain the transcript of the session.  If this parameter is omitted, the file typescript is written.

DESCRIPTION

       The transcript is written to file, or appended to file if the -a option is given.  If no file name is given, the transcript is saved in the
       file typescript.

       The script ends when the forked shell exits.

       This program is useful when you are using a CRT and want a hard-copy record of the dialog (for example, a technical writer might create	an
       example of a working session this way).

       If you specify the -a option and the file does not exist, it is created.

       If you do not specify the -a option and the file exists, it is replaced.

RESTRICTIONS

       The  script command requires a streams based terminal.  In single user mode, streams may not be enabled.  Under these circumstances, script
       will exit with no action.  If you are the superuser and need to run this command in single user mode, use the  following  special  instruc-
       tions.

   Enabling Streams
       If it is necessary to enable a streams environment in the single user mode, enter the command /sbin/init.d/streams.  This command is avail-
       able to the superuser only.
