Question Procmail: match pattern then pass to shell script


I have a simple lookup table as follows:Using Procmail, if I receive an email for, I want to check to see if it needs redirecting based on the information in my lookup table. I'm unsure of the best method.

I tried egrep and awk but neither can accept a pattern from stdin, so I wrote a shell script (alias.bedrock is the lookup table):
awk "/$1/ {print \$2}" alias.bedrock
However, I don't know how to get procmail to pass the 'user@' portion of the address to the shell script. My recipe starts something like this:
:0 wc:
* ^X-Original-To:.*
| ./<script> (user@) alias.bedrock | $SENDMAIL
As you can see, I somehow need to capture the value of .* in the regular expression and pass it to my script.

1. Is this the best method to achieve this?
2. Is anyone able to offer some assistance please?

Many thanks,

The value returned by a regular expression is stored in $MATCH

The value of the recipient of an email is stored in $2 The sender is stored in $1

Hope that helps
