Decode email
In pine email, when you receive an email with an attachment, the content of the attachment is incoded (content-transfer-encoding: base64). I am trying to write a shell script that will read the mail file, and it will save the attachment of an email to a directory.
I want to do this by reading mail file, save the content of the attachment into a variable, and saving that content in a directory with the same file name that it had, which is also specified in the mail file. I'm trying to figure out how I can decode the attachment in my shell script so that I can save the unencoded content of the file, rather than the hex code that is shown in the mail spool file.
Any ideas? Thanks for the help.

lr_getbody
LR_GETBODY.IN(1) LogReport's Lire Documentation LR_GETBODY.IN(1)
NAME
lr_getbody - Extract file, sender and subject information from an email
SYNOPSIS
eval `lr_getbody [-c content-type] <messagefile>`
DESCRIPTION
lr_getbody reads an email message on stdin (or specified as argument), will extract the submitter address and the subject from that email.
It will also extract the biggest attachment or the first one having a content-type matching the content-type argument.
This information is passed to the caller by printing that information in a format suitable for eval. The following variable will be printed
on STDOUT:
lr_getbody_SUBMITTER
Email address of the submitter. That is the first email that is found in the headers (searched in the following order): Reply-To, From,
Sender. This will only contains the address portion (without the <>).
lr_getbody_TO
The email address to which the email was sent.
lr_getbody_SUBJECT
Subject of the message. That string is sanitized.
lr_getbody_DATE
The date of the message. That string is sanitized.
lr_getbody_FILE
Path to the temporary file holding the found attachment.
lr_getbody_OK
This will be set if the operation was completed successfully. It is possible for lr_getbody to fail to extract the attachment, but the
header information might still be available.
This script is used by lr_processmail(1) and lr_rawmail2mail(1).
