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!!

mime-tool
MIME message tool(1) General Commands Manual MIME message tool(1)
NAME
mime-tool - a simple program to construct MIME messages with attached files
SYNOPSIS
mime [ -dDvV ] [ -S subject ] [ -F from-address ] [ -T to-address ] [ -C carbon-copy address ] [ -P prolog-text ] [ -E epiplogue-text ] [
-B boundry ] [ -O overall content-type ] { [ -78abiquxopm ] [ -t content-type ] filename }
DESCRIPTION
The mime program constructs MIME messages with attached files. The user can specify the content type (application/octet-stream, text/plain
or a user specified type), content type encoding (7bit, 8bit, binary, base64 and auto-detect), content disposition (attached or inline) and
the content boundry string. The user can also specify some mail related options: subject, from-address, to-addres, carbon-copy addres,
prolog-text and epilog-text.
The output of the MIME-tool program can be sent directly to the mail, mailx or sendmail commands (or any other command that accepts RFC-822
formatted messages).
NOTE: Specifying 7-bit encoding for an attachment that contains 8-bit data will convert any data bytes whose high-bit is set to question
marks.
OPTIONS
-7 7-bit ASCII encoding
-8 8-bit ASCII encoding
-a application/octet-stream content type
-b binary encoding
-d low detail debugging
-D high detail debugging
-s write a subpart
-i disposition: inline (instead of attachment)
-q quoted-printable encoding
-c content-type
explicit content type
-t text/plain content type
-o omit disposition line
-u unknown encoding, auto-detect
-v verbose messages
-V very verbose messages
-x base64 encoding
-p copy existing MIME part
-o omit content-disposition
-m omit content-transfer-encoding
-n filename
override the filename in the disposition header
-N don't add a filename parameter in the disposition header
-0 no-op
EXAMPLES
Using MIME-tool to write a mail message to a file:
mime -S "test message" -F me@foo.net -T someone@somewhere.net file1 > test.msg
Using MIME-tool with the mail command:
mime -S "test message" -F me@foo.net file1 | mail someone@somewhere.net
Using MIME-tool with the mailx command:
mime -S "test message" -F me@foo.net file1 | mailx someone@somewhere.net
Using MIME-tool with the sendmail command:
mime -S "test message" -F me@foo.net file1 | sendmail someone@somewhere.net
VERSION
This is version 1.5.topal3 from June 2009.
KNOWN BUGS
Most of the header values are not properly quoted or folded, so long or complex values for these headers may cause problems. Specifically,
the from-address, to-address, carbon-copy-address and content-type headers may not be properly quoted or folded.
For some reason, certain e-mail clients (espcially from a large software company located in Redmond, Washington) don't seem to recognize
file attachments as attachments, but instead displays them as inline attachments. (maybe this isn't MIME-tool's fault, but I've gotten a
few e-mails about it, so I'm mentioning it here)
AUTHOR
mime is written by Jeffrey Dutky <dutky@bellatlantic.net>
Oscar Esteban spotted an off-by-one error in the base64 encoding function.
Sergey Lapin spotted a bug in the filename header construction.
Chris Hemphill noticed that the documentation (this manual page and the README file) didn't include any examples of how to call the program
with common mail commands.
Some additional fixes and additions by Phil Brooke to support Topal.
