comment How can I disown a running process and associate it to a new screen shell?
The secondary/implicit issue in this question I can't fathom is...why did the shell choose to disown a suspended job when there is a newer/just launched one in background that doesn't even need/wait for stdin? This is the treatment I've gotten used to so don't know what went different here...

Yeah that saved it, thanks! I read the author's website how it works better than similar or older tools eg. for ncurses programs.

From questions like unix.stackexchange.com/a/4039/13496 I'm hearing about retty and neercs. Hmmm... wonder if there's smth like a "screen here" layer before I run a process next time should I lose the top terminal in the future, that will make it easy to snap back in the stdin/out/err

comment How to schedule something run once using anacron?
Just realized that too won't work if server comes back up eventually, anacron runs, and those at schedules are already in the past--would be interpreted as tomorrow

comment How to schedule something run once using anacron?
If so, thanks--I'll have to re-check my observations on that though. For sure crontab doesn't act like that, so based on your comment, I may need to convert some of my mission-critical crontab lines to at jobs launched by anacron.daily to run at their specific crontab times

Sounds like could be part of the solution; how would my programs go about scheduling (or avoid scheduling) arbitrary jobs+future parameters like they do now with at? To run only once at a future date/hour/minute, or next uptime following that appointment.

That helped me understand how the stuff in /etc/anacrontab works, thanks. I considered hacking my own interface on top of anacron, till I noticed its built-in scheduling isn't more granular than a full day (contrasted with 1min in cron).

batch "now + 1 minutes" <<< "uptime" gives batch accepts no parameters like you said. Guess that cements that possibility for Ubuntu, anyway. Ability to schedule is essential.

From the man page: executes commands when system load levels permit; in other words, when the load average drops below 1.5, or the value specified in the invocation of atd. I wouldn't want it limited by system load though

comment need portable crontab host-checking/failover logic across Linux & Cygwin
Note that in Linux the test could be collapsed to ping -A -c5 $partner || partner=nnn however I needed to add the 6 7 and |grep ... for Cygwin compatibility.
