Why am I getting "Can't find string terminator "'" anywhere before EOF at -e line 1" when I try to run a Perl one-liner on Windows? [duplicate]

I am trying to run the following on Windows with 5.14.2

C:\Perl>perl -e 'print "Hello World \n"'
Can't find string terminator "'" anywhere before EOF at -e line 1.

What am I missing?

You're missing a decent shell with sane and well-defined quoting rules. On Windows, only the double quote is considered a quote, and the escaping rules are poorly defined and inconsistent. Try:

perl -e "print qq{Hello World \n}"

I strongly recommend avoiding anything but the very simplest one-liners on Windows. (Another problem with Windows one-liners is that the Windows shell doesn't expand wildcards. If you use *.txt on the command line, it'll look for a file named literally *.txt. You'll run into that later.)

On Windows, what you typed is equivalent to:

perl -e "'print" "Hello World \n'"

That is, the code Perl is trying to execute is 'print with @ARGV containing the single string Hello World \n'. (That's not a newline, that's a backslash followed by n).
