I think you completely misunderstand "support" here. Windows's cmd.exe "supports" single quotes, just like it supports a, b, 3, 7, 9, and =. They are just ordinary characters. A double quote has an entirely different kind of support. It will allow having spaces or other special characters as part of a command argument instead of their normal interpretation (where a space, for instance, would mean a break between arguments) and doesn't itself become part of the argument.

C:\windows\system32>c:/perl/bin/perl -we'print "Hello World\n"'
Can't find string terminator "'" anywhere before EOF at -e line 1.

Here, perl is getting as it's first argument "-we'print". It interprets the -w and -e switches, and finds that the code supplied for -e is the beginning of a single-quoted perl string, but with no end-quote, causing the error, just as if you had a perl program file consisting of just:

'print

If you add -leBEGIN{for(@ARGV){print$_}} before the -we, you can see that the space causes what comes after to become a separate argument to perl:

C:\windows\system32>c:/perl/bin/perl -leBEGIN{for(@ARGV){print$_}} -we
+'print "Hello World\n"'
Hello World\n'
Can't find string terminator "'" anywhere before EOF at -e line 2.

If you think cmd.exe does something special with single quotes, show an example.

It's entirely possible that I'm missing something here, but I thought I answered the OP's requirement. The original command line code was:


perl -MURI::Escape -MLWP::Simple -e "$t = get "http://www.cgiscript.ne
+t/encrypt_index.htm"; print uri_unescape $t;"


Since his double quoted string (the URL) doesn't have any escaped characters in it, he should be able to get away with using single quotes around it.

The following works at the command line:

$perl -we"print 'http://somewhere.com'"

If I'm missing something, please excuse my newness at this.

Sorry for giving you a hard time. In:

perl -we"print 'http://somewhere.com'"

perl is supporting the ' as a special character (that quotes a non-interpolating string), not Windows.
