w: GNU w output header includes output from uptime

[aliwithay]

The header in GNU version contains the output from uptime as part of the header.

 15:12:54 up  5:47,  1 user,  load average: 0.68, 0.61, 0.74
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT

coreutils already has an implementation for uptime so the code for this already exists.

[aliwithay]

Wondering if the best way to handle this would be to duplicate the code from uptime, or is there a way to call the coreutils implementation somehow?

[cakebaker]

uptime is a crate on its own (https://crates.io/crates/uu_uptime), so, at least theoretically, it should be possible to reuse it in this way in w.

or move the critical functions into uucore

Thanks for the suggestions. Most of the functions are simply formatting functions which probably don't need to be in uucore. I think using the uptime crate might be okay for this. I will take a look into it.
