in reply to why does -e work and not \n on strawberry perl

Double quotes usually work better for enclosing command-line scripts in windows shells. Also, windows shells typically add a newline, so you can leave off printing one at the end of your script. If you need \n to work, try using a qq string, like this:

perl -e "print qq[Howdy\nWorld\n]"
