Caveat: this is the "dummy" forum, right?
That's where I belong. How do I find mimencode? I did a 'which mimencode' from the command line, and I can't find it. I'm running on a solaris 2.6. Thanks

mimencode (also known as mmencode) is part of the metamail package. You can get a solaris version here: http://www.ibiblio.org/pub/packages/solaris/sparc/
Download to /tmp and "gunzip" it. Then do a "pkgadd -d /tmp"

You should now have mimencode installed in /usr/local/bin

Then you can run something similar to the following script (pipe it to mailx)

#!/bin/bash
#
# Script: sendfile
#
# Purpose: Send the specified file via email as a MIME
# attachment to the specified address.
#
# Author: Anthony E. Greene <agreene@pobox.com>
#
# License: GPL <http://www.gnu.org/>
#
# Note: This script does not include any error checking, so
# it should only be called from within other scripts.
# The correct syntax for using this script is:
#
# sendfile filename user@domain | /path/to/sendmail -t
#

# First we set up some global variables.
# Some code should be added to verify the commandline arguments.
sender=you@yourdomain.com
filename=$1
basefile=`/bin/basename $filename`
recipient=$2

echo From: $sender
echo To: $recipient
echo Subject: File $basefile
echo MIME-Version: 1.0
echo "Content-Type: multipart/mixed; Boundary=\"sendfile-attachment-boundary\""
echo
echo --sendfile-attachment-boundary
echo 'Content-Type: text/plain; charset=us-ascii'
echo
echo This is a MIME encoded message. If your mail software
echo cannot properly handle the attached file, you may need
echo to get a MIME-aware mailer.
echo
echo --sendfile-attachment-boundary
echo "Content-Type: application/octet-stream; name=\"$basefile\""
echo Content-Transfer-Encoding: base64
echo "Content-Disposition: attachment; filename=\"$basefile\""
echo
/usr/bin/mimencode $filename
echo --sendfile-attachment-boundary--

Thanks! I'll give it a try, but I'm not an SA, and in the past they haven't given me root access to install packages.
I'll see what I can do. The responses have been very helpful. Thanks again
