Marco_ALT — Sun, 04 Oct 2009 09:55:17 GMT

Hello

I have an operations which give the output in a variable $out

I want to send this output by e-mail, so guys know that the job has been finished.

Simply, i need to write the variable $out to a file, after that i can send it by e-mail.

Can you please help with this?

Why do you need to write the value to a file? Am I over-simplifying this?:

echo "Output of operation is <${out}>" | mailx -s "Output of operation" my.email@myaddress.com

Won't that do?

Sure if you want:

echo ${out} > /tmp/myfile.txt

cat /tmp/myfile.txt | mailx -s "Output of operation" my.email@myaddress.com

To a CSV file??? what are you trying to put in comma delimited format??

Maybe you need tyo define your problem statement a bit further

it seems like a Java application error not HP-UX . Did you use a java code to get this output ?

Where? On stderr or in tmp/myfile.txt?

If your variable may contain spaces, semi-colons and/or other characters with a special meaning to the shell, put double quotes around it.

echo "${out}" > /tmp/myfile.txt

The semi-colon (;) ends one shell command and begins another. If your variable contains semi-colons and the variable expansion is not quoted, the first semi-colon will terminate the echo command and the rest of the variable content will be interpreted as shell command(s), most likely causing error messages.

Not hardly, a real shell doesn't look for a ";" after variable expansion:
$ x="abc;def"
$ echo $x
abc;def

The reason you quote things is because you want to preserve the whitespace.

>echo "${TAP OUT}" > file02.txt

You can't do that. You can't have spaces in a variable name. You would get:
ksh: "${TAP OUT}": bad substitution

Marco_ALT — Thu, 08 Oct 2009 07:11:56 GMT

when i substitute with the following

x="TAP OUT"
echo $x > file02.txt;

i received the e-mail contaning "TAP OUT" as the body!!

i need to subistitue with the variable value
ie $TAP OUT not the name char "tap out"

shall i do it like
x="${TAP OUT}"
echo $x.........
?
plz advise

You can't have a variable with embedded spaces.

If you want to do variable "indirection":
$ x=9
$ y=10
$ z=x
$ eval echo \$$z
9
