I had to send a mail using only command line.
|
||
|
I was surprised it isn't straightforward at all.
|
||
|
I didn't had `pine` nor `mutt` or anything like that.
|
||
|
Just `mail` and `mailx`.
|
||
|
|
||
|
What Internet say (via google) is
|
||
|
|
||
|
<code class="zsh">
|
||
|
uuencode fic.jpg fic.jpg | mail -s 'Subject'
|
||
|
</code>
|
||
|
|
||
|
I tried it.
|
||
|
And it works almost each times.
|
||
|
But for my file, it didn't worked.
|
||
|
I compressed it to `.gz`, `.bz2` and `.zip`.
|
||
|
Using `.bz2` format it worked nicely, but not with other formats.
|
||
|
Instead of having an attached file I saw this in my email.
|
||
|
|
||
|
<pre>
|
||
|
begin 664 fic.jpg

end
|

</pre>

Not really readable.
|
||
|
After some research I found the solution.
|
||
|
Use MIME instead of `uuencode`.
|
||
|
|
||
|
Finally I made it manually using `sendmail`.
|
||
|
I didn't dare to use `telnet`.
|
||
|
The command to use is:
|
||
|
|
||
|
<code class="zsh">
|
||
|
sendmail -t -oi < mailcontent.txt
|
||
|
</code>
|
||
|
|
||
|
Of course you need to create the `mailcontent.txt` file.
|
||
|
It should contains:
|
||
|
|
||
|
<pre>
|
||
|
From: from@mail.com
|
||
|
To: to@mail.com
|
||
|
Subject: View the attached file
|
||
|
Mime-Version: 1.0
|
||
|
Content-Type: multipart/mixed; boundary="-"
|
||
|
|
||
|
This is a MIME encoded message. Decode it with "Decoder"
|
||
|
or any other MIME reading software. Decoder is available
|
||
|
at <http://www.etresoft.com>.

Content-Type: image/jpeg; name="fic.jpg"
|
||
|
Content-Transfer-Encoding: base64
|
||
|
Content-Disposition: inline; filename="fic.jpg"

|
||
|
...
|
||
|
</pre>
|
||
|
|
||
|
And to obtain the "encoded" file in base64 I used:
|
||
|
`uuencode -m fic.jpg fic.jpg`
|
||
|
|
||
|
That is all.
|
||
|
Sometimes technology is so easy to use.
|
||
|
Si j'en ai besoin encore quelques fois, je pense que j'écrirai un émetteur de mail en shell.
