Again, command.com/cmd.exe doesn't have "yes" so I still prefer "echo"

which is available in every shell I have at my disposal (all *nix

shells, command.com, cmd.exe, and Power Shell).  But the

shell-escaping is another layer of complexity.  Using cmd.exe and

command.com expects double-quotes rather than single quotes (though

certain versions of sed might be smart enough to reparse the

arguments for single-quote escaping), so one might have to do use

single-quotes and then tell sed to use an escape sequence.



sed -e "s/.*/Hello, world\x21/" -e q
