We need sed -n ?

[hemanth]

Some like sed('-n','/FOO/,/BAR/p',cat("cats.txt"));
says sed: option not recognized: n

This seems like a reasonable addition. @hemanth if you're able to submit a PR, I'd be happy to take a look.

I don't even recall why I had created this issue!

Anyway,

By default, each line of input is echoed to the standard output after all of the commands have been applied to it. The -n option suppresses this behavior.

Let see what best I can do here.

I'm going to go ahead and close this, since it doesn't seem that useful. It looks like this would only mean that a sed() call returns the empty string. A suitable workaround would be to just ignore the return value instead.

If other sed modes get supported, like the /p mode, then we can revisit this. Feel free to open this if there's some use-case I'm overlooking.
