Linux really uses shell scripts to do timed mission critical nohup

There are a lot of articles on the Internet to teach you to use scheduled tasks, so other nonsense I will not say more

I here directly have sh to do timing, just a little people do not know, must use Nohup, otherwise the user exits terminal, SH task will be automatically terminated

Suppose there is a tash.sh, note the following, are the essence

Start is: nohup/home/spex/bin_proddemo/task.sh & make sure to take the path full, absolute address

Just quit, remember to quit!!! exit the terminal with Exit !! Do not exit directly. Otherwise it's useless.

Then look at the PS aux|grep task

You can see it running right there.
