: Hmph. Just preprocess the file with sed 's-\\-\\\\-g'. Or, if you really
: like backslashes, sed s/\\\\/\\\\\\\\\/g. Or, if you're a masochist, sed
: s/\\(\\\\\\)/\\\\\\1/g? sh -c "sed s/\\\\(\\\\\\\\\\\\)/\\\\\\\\\\\\1/g"?

No, it isn't.  The official Perl Slogan is: There's More Than One Way To Do It.

There are still a few things sed is good for...   :-)

And you'll note that I did mention sed in my original message.

But "hmph", yourself.  You still haven't posted "a solution that ALSO works
on all the \c machines."  Your -n solution doesn't work on a \c machine,
and your \c solution doesn't work on a -n machine.  At least it's symmetrical.

(By the way, what makes you think s/\\\\/\\\\\\\\/ is a solution?  It only
translates \\, not \c.)

Please don't call me a "Perl lord".  I'm merely trying to follow the ancient
wisdom that "he who wants to be the greatest among you must become the
servant of all."

The leader of this particular jihad doesn't believe in holy war.  Pity.
