Hi

If I understand you correctly :

[teal]([/teal]
    echo [i][green]'Need to amend the below email information in the body of the email.'[/green][/i]
    ps -ef [teal]|[/teal] grep [i][green]"Srv"[/green][/i]
    echo [i][green]'Srv634P -> used for client acecssing.'[/green][/i]
    echo [i][green]'Srv634 -> Used for server acessing.'[/green][/i]
[teal]) |[/teal] mailx -s [i][green]"Server Currently Running "[/green][/i] xyz@gmail[teal].[/teal]com

Please let me know how to remove the 3rd line which we used to search in the unix command.

Thanks a lot for providing solution.

Hi

Please let me know how to remove the 3rd line which we used to search in the unix command.

There are two usual ways :
[ol]
[li]Use another [tt]grep[/tt] call to exclude lines containing "grep" :

ps -ef [teal]|[/teal] grep [i][green]'Srv'[/green][/i] [teal]|[/teal] grep -v [i][green]'grep[/green][/i]'

[/li]
[li]Use a regular expression that matches the needed string but not matches itself :

ps -ef [teal]|[/teal] grep [i][green]'[S]rv'[/green][/i]

[/li]
[/ol]

Hi

That is more difficult question, as [tt]echo[/tt] is not fully portable. So you have to pick one of the solutions that works on your system :

echo   [gray]# without parameters usually displays just a newline[/gray]

echo [i][green]'line one[/green][/i]
[i][green]line two[/green][/i]

[i][green]line four ( yepp, line three was empty and so will be line five )[/green][/i]
[i][green]'[/green][/i]      [gray]# not echo's trick, but the shell's : embed literal newlines in the parameter[/gray]

cat [teal]<<[/teal]ENDOFTEXT [gray]# similar as above, but with cat and here-document[/gray]
line one
line two

line four [teal]([/teal] yepp[teal],[/teal] line three was empty and so will be line five [teal])[/teal]

ENDOFTEXT

echo [i][green]'line one[/green][/i][lime]\n[/lime][i][green]line two'[/green][/i]   [gray]# some implementations interpret embedded \n as newlines[/gray]

echo -e [i][green]'line one[/green][/i][lime]\n[/lime][i][green]line two'[/green][/i]   [gray]# other implementations does it only when asked to by using the -e option[/gray]

echo $[i][green]'line one[/green][/i][lime]\n[/lime][i][green]line two'[/green][/i]   [gray]# somehow similar, but here Bash interprets the \n, not echo[/gray]

[b]printf[/b] [i][green]'line one[/green][/i][lime]\n[/lime][i][green]line two[/green][/i][lime]\n[/lime][i][green]'[/green][/i]   [gray]# printf is standard, just note that it outputs no implicit newline[/gray]

Thanks for your solution. All the options worked out.

Cam tell me also let me know how to make the 1st line with bold and underlined.

1st line "Instance Description/"

 

[feherke]

Hi

Cam tell me also let me know how to make the 1st line with bold and underlined.

By default e-mails are plain texts, so no formatting. Some clients may honor some conventions of plain text formatting, like *bold* and _underline_, but that is each client's own decision.

What you can do, is send the content as HTML document. Then you can use some usual HTML and CSS formatting. ( Not all. And they will not appear the same way in every client. )

To tell the mail clients the content is HTML document, add those [tt]-a[/tt] parameters to [tt]mailx[/tt] as below :

[teal]([/teal]

cat [teal]<<[/teal]ENDHEADER
<html>
<body>
<pre>
ENDHEADER

    ps -ef [teal]|[/teal] grep [i][green]'[S]rv'[/green][/i]

cat [teal]<<[/teal]ENDFOOTER
</pre>
<p><b><u>Instance Description :</u></b></p>
<p>
Srv634P -&gt; used for client acecssing.<br>
Srv634 -&gt; Used for server acessing.
</p>
</body>
</html>
ENDFOOTER

[teal]) |[/teal] mailx -s [i][green]"Server Currently Running "[/green][/i] -a [i][green]'MIME-Version: 1.0'[/green][/i] -a [i][green]'Content-Type: text/html'[/green][/i] xyz@gmail[teal].[/teal]com

[small][maroon]Warning ![/maroon] The above code was not tested.[/small]

thanks for your update.

I am getting the below error when I tried to execute the above code.

mailx: illegal option -- a

 

[keerthi2016]

I have pasted the given code html in the name of testt.html and called the html code in the shell script.

home/unix >cat testt.html

(

cat <<ENDHEADER
<html>
<body>
<pre>
ENDHEADER

ps -ef | grep 'rv'

cat <<ENDFOOTER
</pre>
<p><b><u>Instance Description :</u></b></p>
<p>
Srv634P -> used for client acecssing.<br>
Srv634 -> Used for server acessing.
</p>
</body>
</html>
ENDFOOTER

/home/unix]$ ksh -x lkl.sh
set -x
cat testt.html

But I could see the emails are not sent to the id.

 

[keerthi2016]

I am wrongly executing the html tag. it would be great if you can help me how to execute the html tag.

Hi

mailx: illegal option -- a

That is bad. That [tt]-a[/tt] option is an addition, not part of the standard. Some such tools have it, others not.

You need [tt]-a[/tt] or something equivalent to specify a mail header. The manual of the [tt]mailx[/tt] implementation on my machine describes it like this :

[pre]  -a Specify additional header fields on the command line such as "X-
Loop: foo@bar" etc. You have to use quotes if the string con‐
tains spaces. This argument may be specified more than once, the
headers will then be concatenated.[/pre]

Look in the manual of your [tt]mailx[/tt] to see whether it mentions another way to specify headers.

Alternatively, check if [tt]sendmail[/tt] is available on your machine.

[keerthi2016]

can you please tell me how to run the file test.html file.

Previously i have run the file with the .sh extension hence i got the error.

 

[SamBones]

Sendmail can do it. Something like this...

export SUBJECT="Servers Currently Running"
export MAILTO=xyz@gmail.com

(
cat <<-EMAILHEADER
To: ${MAILTO}
Subject: ${SUBJECT}
MIME-Version: 1.0
Content-Type: text/html
Content-Disposition: inline
EMAILHEADER

cat <<-DOCHEADER
<html>
<body>
<pre>
DOCHEADER

    ps -ef | grep '[S]rv' | grep -v grep

cat <<-DOCFOOTER
</pre>
<p><b><u>Instance Description :</u></b></p>
<p>
Srv634P -> used for client accessing.<br>
Srv634 -> Used for server accessing.
</p>
</body>
</html>
DOCFOOTER

) | /usr/sbin/sendmail ${MAILTO}

 

[feherke]

Hi

SamBones, an empty line is missing there, right before closing the EMAILHEADER here-document, to separate e-mail headers and e-mail body.
