How to read email using mailx in shell script or perl
Hello,

I am new to mailx and perl and I need help.

I need create a shell script to read the mails on the SUN server, then parse the subject line and message body of each email to extract particular data so that I can pass these data fields in as application parameters to invoke a java client application from the script. This logic need to be run every so many minutes to check for new email in the user's system mailbox.

I was thinking of using mailx in shell script. Is there a way I can parse the mail stream and pipe the extracted data to the java application inside mailx? Or do I have to copy the mail into a file, exit/quit mailx, then process the contents in the file later from the shell script? Or is there a better way using Perl?

Thank you!!

rt-email-dashboards-4

rt-email-dashboards(8)					     Request Tracker Reference					    rt-email-dashboards(8)

NAME

       rt-email-dashboards - Send email dashboards

SYNOPSIS

	   rt-email-dashboards [options]

DESCRIPTION

       This tool will send users email based on how they have subscribed to dashboards. A dashboard is a set of saved searches, the subscription
       controls how often that dashboard is sent and how it's displayed.

       Each subscription has an hour, and possibly day of week or day of month. These are taken to be in the user's timezone if available, UTC
       otherwise.

SETUP

       You'll need to have cron run this script every hour. Here's an example crontab entry to do this.

	   0 * * * * /usr/bin/perl /opt/rt4/local/sbin/rt-email-dashboards

       This will run the script every hour on the hour. This may need some further tweaking to be run as the correct user.

OPTIONS

       This tool supports a few options. Most are for debugging.

       -h
       --help  Display this documentation

       --dryrun
	       Figure out which dashboards would be sent, but don't actually generate or email any of them

       --time SECONDS
	       Instead of using the current time to figure out which dashboards should be sent, use SECONDS (usually since midnight Jan 1st, 1970,
	       so 1192216018 would be Oct 12 19:06:58 GMT 2007).

       --epoch SECONDS
	       Back-compat for --time SECONDS.

       --all   Ignore subscription frequency when considering each dashboard (should only be used with --dryrun for testing and debugging)
