KornShell (ksh) code to send attachments with mailx and uuencode?
Solution 1
You have to concat both the text of your message and the uuencoded attachment:
$ subject="Something happened"
$ to="[email protected]"
$ body="Attachment Test"
$ attachment=/path/to/somefile.csv
$
$ cat >msg.txt <<EOF
> The message is ready to be sent with the following file or link attachments:
>
> somefile.csv
>
> Note: To protect against computer viruses, e-mail programs may prevent
> sending or receiving certain types of file attachments. Check your
> e-mail security settings to determine how attachments are handled.
>
> EOF
$ ( cat msg.txt ; uuencode $attachment somefile.csv) | mailx -s "$subject" "$to"
There are different ways to provide the message text, this is just an example that is close to your original question. If the message should be reused it makes sense to just store it in a file and use this file.
Solution 2
Well, here are the first few problems you've got.
You appear to be assuming that a mail client is going to handle uuencoded attachment without any headers. That won't happen.
You're misusing I/O redirection: uuencode's output and the here-document are both being fed to mailx, which can't happen.
You're misusing uuencode: if one path is given, it's just a name to give the decoded file, not an input file name. Giving the file twice will assign the same name to the decoded file as that which was read. The -m flag forces base64 encode. But this still isn't going to provide attachment headers for mailx.
You're way better getting a copy of mpack, which will do what you want.
If you must do it, you could do something like this:
cat <<EOF | ( cat -; uuencode -m /path/to/somefile.csv /path/to/somefile.csv; ) | mailx -s "$subject" "$to"
place your message from the here block in your example here
EOF
There are lots of other possibilities... but this one still has the here document as in your example and was easy off the top of my head, and there's no temp file involved.

I need to attach a file with mailx but at the moment I am not having success.
Here's my code:
subject="Something happened" to="[email protected]" body="Attachment Test" attachment=/path/to/somefile.csv uuencode $attachment | mailx -s "$subject" "$to" << EOF The message is ready to be sent with the following file or link attachments: somefile.csv Note: To protect against computer viruses, e-mail programs may prevent sending or receiving certain types of file attachments. Check your e-mail security settings to determine how attachments are handled. EOF
Any feedback would be highly appreciated.
Update I have added the attachment var to avoid having to use the path every time.

Nano Taboada over 15 yearsThanks much! Yes I've seen there's mutt to that can do simple attachments but since I'm not root in that box I'd have to deal with any mailx hack.

Thomas Kammeyer over 15 yearsYou have and older version of uuencode, before it provided base64 encoding... you could still get mpack and just compile it for use locally under your account... that's what I'd probably do.

Nano Taboada over 15 yearsThanks for the reply! So the msg.txt is being created by the EOF then reused in the last line?

Nano Taboada over 15 yearsMy bad! i've spaced the cat >msg.txt <<EOF
