Thanks Zaxxon,

I had tried variations of that. I don't really have anything to post because I was stuck at the beginning. Turns out the problem is with my understanding of procmail since your code works fine if I pipe to my script from another script. Here's the procmailrc if anyone has any knowlege of this stuff:

Code:
:0 b
|$HOME/test.sh

My understanding is that this should pipe the body of the email to the script test.sh. As it stands right now, the script is triggered but there doesn't appear to be anything piped. I've used your suggestion in a script named "test.sh":
Code:
while read LINE; do
   echo ${LINE}  > t.log 
done

exit 0

if I write a small script that says:
Code:
echo "test"

save it as t.sh and run it at the command line like this:
Code:
./t.sh|./test.sh

then the file t.log is created and contains the line:
Code:
test

If I send an email to this mailbox the script test.sh is triggered but the file t.log contains only a blank line. That's where I'm at and I realize this isn't a procmail forum, but any help will be appreciated.

shcomp

SHCOMP(1)						       Korn shell utilities							 SHCOMP(1)

NAME

       shcomp - compile a shell script

SYNOPSIS

       shcomp [ options ] [infile [outfile]]

DESCRIPTION

       Unless  -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with
       the same effect as the original script.

       Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly.

       If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages	that  need  to	be  translated	to
       locale specific versions for internationalization.

       If  outfile  is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from
       standard input.

OPTIONS

       [D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization.	[n noexec] Displays  warn-
       ing messages for obsolete or non-conforming constructs.	[v verbose] Displays input from infile onto standard error as it reads it.

EXIT STATUS

       0
	 Successful completion.
       >0
	 An error occurred.
