R420

P.S. Точнее, как я понимаю, это не приложений "запущеннные", а клиенты X-сервера, причём клиенты именно того X-сервера на котором мы делаем команду.

После запуска xwininfo

Подавляющее большинство (все?) X-приложений можно выполнять удалённо: приложение выполняется на компьютере удалённом на десятки километров, а отображается но моём локальном компьютере.
Это - в порядке напоминания...
Но про это у нас есть отдельная тема: удалённый запуск графических X-приложений + её давно уже следует освежить ... в новых реалиях.

P.S. И эти возможности, для истинного UNIX-оида куда интереснее, чем всякие возможности удалённого рабочего стола (на которые так прутся пользователи пришедшие из Windows ... особенно в Astra Linux - протокол RDP (Remote Desktop Protocol) и т.п.), или разные VNC для удалённого управления компьютером по сети (VNC : TeamViewer, NoMachine - удалённый рабочий стол).
