Help: How can I run less commnd?

[Nadim147c]

I'm trying to run the less command from js but following code isn't working

await $({ input: content })`less ${"+" + lineNumber.trim()}`

I also tried it with verbose but not working. So, is there anyway to run the less command?

In order to run less command you need a tty or a pty. zx does not provide those.

Can use you cat instead?

Or consider something like node-pty.

Hey, thanks for letting me know.

I was initially using cat (tail +n). But I needed to preview the previous line, which can't be done with cat or tail command.

I was trying node-pty to work with less command but failed. I know it's outside zx, But I would appreciate if you could share any snippet or something.

I couldn't find any NPM package that helps me to do that. I guess I have to make my own.

Thanks anyway.
