Which of 20 Terminals has mc on PATHx?

[chris glur <crglur gmail com>]

I've been trying to solve this for ten years!
Find which Workspace, terminal has a particular mc:Path/File ?
=> howmany mc are currently running
-> System.Execute pgrep mc   | wc -l  == 22 & last = 13982
=> Add one more looking at: /.mc/tree & /.mc/init == 14486

=> Use `mc` to search /.mc/* for  init  || tree  == nX
=> Examine /proc/14486/*
-> System.Execute grep -n tree /proc/14486/*
== Binary file /proc/14486/exe matches
-> System.Execute ls -l /proc/14486/exe == only a link
                                  /proc/14486/exe -> /usr/bin/mc
-> System.Execute less /proc/14486/cmdline == mc
=> Is /.mc/tree listed as an 'open file' ?
-> System.Execute lsof | grep tree == nX
-> System.Execute lsof | grep mc == !! bad choice !!
-> System.Execute lsof | grep init ==na
====
Just ignore "-> System.Execute" except to note that free/small-ETHO,
is even more visual than mc.

How do YOU know which mc is ALREADY open on a certain PATH/file?

== TIA.
