FR: Have `pxtree pxtree` work.

[ilyagr]

I occasionally want to know the PID of the shell I'm in or of the terminal I'm in. The natural thing to do is pxtree pxtree, but that cleverly filters out itself and shows nothing.

I wish it worked. I am not sure whether the best solution would be to except pxtree pxtree, or to simply disable the self-filtering behavior for pxtree. I suppose there could also be a pxtree --self option.

ptop might also benefit from being able to show its own tree. Perhaps it would be good to disable self-filtering in tree mode.

A number of shells provide the shell PID using echo $PPID. In fish you can echo $fish_pid.

So you could do pxtree $PPID or pxtree $fish_pid to get this info. Not super discoverable though.

What's your usecase? What do you intend to use the shell's / terminal's PID for?

I'm not necessarily against this, but I do want to understand what the root problem is first!

I've wanted to find the tmux process I was in and/or the terminal I was in. pxtree $fish_pid would probably work fine for me, but I didn't think of it at the time. This could also be an option, `pxtree --self`. This is not a crucial feature, of course.
