Using shell scripts different then bash (nushell specifically)

[ArtemChandragupta]

Hi! We can do something like this to poll CPU usage with bash script:

const getUsage = Variable("", {
	poll: [
		5000,
		`bash -c "top -b -n 1 | grep 'Cpu(s)' | awk '{print $2}'"`,
		(out) => parseFloat(out).toFixed(0),
	],
});

But how this can be done with other command shells?

As an example, in nushell same script will be something like this:
sys cpu | get cpu_usage | math avg
and this is much more readable than bash solution, so I want to use this.

Nushell also has a -c flag
Just swap out the bash call to nu
nu -c "sys cpu | get cpu_usage | math avg"
