This question already has an answer here:
This might be a duplicate post but couldn't find one.
I'm looking for a way to run a shell script once at a specific time.
Like run it once at 16:00 then remove from queue.
crontab has no setting for this as I can find since it runs on repeat and not like fire and forget kind I'm looking for.
Anyone got a good suggestion? I want it to be run on Ubuntu 18.04 server version.
