This was a contributed tip by @ragivenk189, nominated for inclusion in our library. These steps use the built-in at command in Unix.
- Go to the desired folder under Unix shell.
- cd to the directory on the Unix where your SAS program resides.
- At the command prompt: type: at 2am tomorrow (Hit enter). It will show at> prompt.
- at> nohup sas test.sas (hit enter)
The nohup utility can be used when it is known that command will take a long time to run and the user wants to logout of the terminal; By default, when a shell exits, the system sends its children SIGHUP signals, which by default cause them to be killed.
However, with nohup, background jobs will ignore SIGHUP and continue running, if their invocation is preceded by the nohup command or if the process programmatically has chosen to ignore SIGHUP.
- at> press <Ctrl>+<d> (to save this)
- You can check if it has been scheduled, by typing: at -l. It will list something like this:
job 107225020.a at Friday Oct 26th 2am
If you want to remove the above job from the queue, type: at -r 107225020.a
This command deletes the scheduled job.
If you like to submit a job at a specified date you can type:
at 0815am nov 02
Here the job will run on Nov 2nd at 8.15am.
