It would still be easier to help if you would post a real example of the data you wish to join together, but I think I understand what you are trying to do, so I'll have a go:)

If I interpret you correctly, $1, $2, and $3 are shell variables? Bash or cshell? And you want to use perl to combine the three into a single line and remove any double quote chars.

Unfortunately, I don't have a unix command line at which to try this out. Maybe someone can try it for me and correct my enevitable errors.

perl -pe'$_=@ARGV[0..2]; tr/"\n//d;' $1 $2 $3

That should take the value of your 3 shell variables, join them into a single string, remove any newlines and " characters and print the result back to the command line where you can pipe it to wherever it has to go.

If I have misunderstood you, come back and tell me so and I'll try a little harder:)

hi,
I would prefer the standard shell script.

Scenario should be like that:
$3 has multiple lines.

I need to convert variable $3 which is multiple lines into one single line only. How?

Here is the example of multiple line.

And how to test it? For example, if I have a file contains multiple lines.

Hope to hear you soon.

Thanks.
