This has turned out to be harder than I expected, as all the research so far is all about killing processes (in this case ST3), which unfortunately produces a different end state (and thus beginning state on restart), rather than closing ST3.
ie
pkill -TERM sublime
produces a different outcome to ctrl+q from, within Sublime.
One can start Subime with the subl command (at command line) I was wondering if there was a command to close sublime rather than kill the sublime process.
It does make a difference. Iâm running linux MATE, ST3.2.1.1
Am hoping (niaively) it might be something like xsubl, or subl_quit or lbus (ho ho ho)
Ta very muchly !
