As part of a slightly complex script, I need to tell a server to run a simulation. Normally, I would achieve this by doing
ssh user@server 'simulation/script'
now + 5 seconds
now + 5 sec
now + 5 s
now + 5seconds
now + 5sec
now + 5 s
There's no seconds in at :
man at said :
- specification of a date must follow the specification of the time of day. You can also give times like now + count time-units, where the time-units can be minutes, hours, days, or weeks and you can tell at to run the job today by suffixing the time with today and to run the job tomorrow by suffixing the time with tomorrow.
So instead of
at, you could use a
sleep I think.
man 1 sleep
If you'd like to run
ssh user@server 'simulation/script' without waiting, simply do :
ssh user@server 'simulation/script' &
the command will run in the background.
Moreover, as Rawkode said,
nohup will help there.
So finally :
nohup ssh user@server 'simulation/script' &
with nohup, you can quit your terminal and have the
ssh process alive.
EDIT: if you want to run the
ssh command and close the connection :
ssh user@server 'simulation/script &'
