Abigail-II has provided a good solution. However on a unix system, I would probably 'cheat' a bit -
my $str = 'blah blah';
system("echo '$str' | cmd -option");

I suspect this might even work under DOS too. :)

Update: As 3dan has pointed out, this solution is flawed and doesn't work properly. However I could try to insert back slashes in front of single quotes in the input string, but that's just creating more unnecessary work and not worth the efford.

However I will not reap this node, I will leave it here as a typical negative example of how not to do it.
