How would i mail in html format?(Formatting Help)
I have written a scripts that checks the load average of server and if it is more than 5 it send a mail describing Current Load Average and High CPU/RAM processes .

The problem is I want to send these information in html form .I have done necessary coding to do the same but whenever i try to include the output of following It doesnt seems to be properly formatted.

Code:
echo "Top 10 CPU Utilized Processes" >> /tmp/Load_Average_Check.html
ssh -Tqn $1 ps auxf | sort -nr -k 3 | head -10 >> /tmp/Load_Average_Check.html
echo "-------------------------------------" >> /tmp/Load_Average_Check.html
echo "Top 10 Memory Utilized Processes" >> /tmp/Load_Average_Check.html
ssh -Tqn $1 ps auxf | sort -nr -k 4 | head -10 >> /tmp/Load_Average_Check.html

Output is as below.
Code:
******************************************************* Top 10 CPU Utilized Processes root 28679 2.5 0.0 34916 6688 ?

Its so difficult to understand when i mail the information in plain text i can see the output properly formatted.

Is there any way i can send some part of script output in html while other in plain text ?
I hope i m not confusing ...

HTML treats all white space as a single space, unless <PRE> or similar tags change the formatting. <PRE> looks like plain text but allows hyperlinks, but you have to escape literal &'"<> as &amp; (do amp first) &apos; &quot; &lt; &gt; . If you want to have the pretty fonts and data that aligns, you need a "<TABLE><TR><TD>a1<TD>a2<TR><td>b1...</Table>". You can postprocess UNIX command output to add the necessary tags and escapes using sed or such. Web stuff is a lot easier to script in PERL, as there are libs for all sorts of web stuff, almost PERLs reason for being, but I live without it, so if you want, you can, too.

For the mechanics of sending, there are several ways, and you can see the formats from your own html mail. Many clients send a plain text version along with html mail for primitive recipient client support.

Send an HTML file as email from the command line..

Technically, email is raw text and nothing but raw text, by the way. Whether the client will understand it or just display a mess of tags is wholly up to the client program.

Well, the raw text gets all mime'd up to send an email readable either in plain text or html, a multi-part, for which there are RFC's galore. To send raw email, I guess you might use sendmail barefoot or connect to port 25 of a mail forwarder and do your own esmtp (not that hard).

Here is a bit of the mail headers for an outlook mail message:

Thanks for the reply but i find it little difficult to understand.
Whenever i send the mail with plain text mail get properly formated.
But When the same is done with html tag some part of mail is not properly formatted (Some part= output of commands like ps aux)

maybe a stupid question but what are you using to send the email? Whenever I send such html mails I use sendmail

have you tried mailx -m ? uuencode? sendmail?

Have you ever tried to send output of ps -aux in html format?
Were you able to interpret the output?
I used sendmail as below.
Code:
sendmail  XYZ@ABC.com < /tmp/Load_Average_Check.html
