how to add double quote to a string in Perl

my code looks following:

$id = "PROD121213123";

I am passing this to a function and adding this to it

"\"$wi_id\""

where $wi_id looks like my $wi_id = $_

After "\"$wi_id\"" the value looks like "PROD121213123" which I checked in Eclipse debugg开发者_StackOverflow中文版er (using EPIC)

I am calling curl.exe from Perl and it looks like this "" is omitted during execution. How can I have "" to the string and still execute using CURL?

It sounds like you're doing the equivalent of

my $id = "\"PROD121213123\"";    # String <<"PROD121213123">>
system "curl.exe ... $id ...";   # curl sees <<PROD121213123>>

It's because the quotes have special meaning to the "shell". Command line parsing is a bit of a mess in Windows (nothing to do with Perl), so you might not be able to even pass double-quotes to curl. I'd try using the multiple arg version of system.

You're trying to pass a quotes string to a command which is called though a shell. To accomplice that, you'll need to escape the quotes to hide them for the shell:

my $id = q(\"PRD121212\");
system qq(curl.exe ... $id ...);
