Try this: `perl -e "print qq/XXX/;"` The msdos shell (or whatever they call it nowadays) wants you to use "....". Of course that leads to the problem that you can't use double quotes within the code, so you use an alternative such as `qq//` instead. Alternate quote-like operators such as `qq//` are discussed in perlop. When your actual code has embedded double quotes the command shell parses it wrong. There is some information in this document, if you search its content for the word "quote" http://technet.microsoft.com/en-us/library/cc723564.aspx So for *nix environments, wrap your code in '...', and in Win/dos environments, wrap it in "...".

Thanks Dave, That did it! I just escaped the inner double quotes, and it all worked fine. It's surprising that the Active Perl documentation says nothing about this problem. Well, maybe I shouldn't be surprised - their documentation is a total kloodge.	[reply]

To be fair, this has more to do with the MSDOS prompt than it does with Active Perl.	[reply]

Hmm, let's see how the searching goes no site:perlmonks.org Can't find string terminator "'" at -e line 1 site:perlmonks.org Can't find string terminator "'" at -e line 1 ... 5th page?

This is a Windoze question, not a Perl question: Unless you are using one of the Cygwin shells (bash, zsh, ...), single quotes are not valid delimiters in the Windoze Command Shell. -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l]
