This tiny library allows you to talk to the at(1) system, available on most UNIX machines, to schedule jobs to be run later.

Using at(1) can be much more light-weight than running a full-fledged job-processing system such as Celery if you are running very few jobs, however the performance will be much lower if you are running a considerable amount of tasks.

import unix_at

job = unix_at.submit_shell_job(['touch', '/some/file'])
unix_at.cancel_job(job)
job = unix_at.submit_python_job(os.mkdir, 'now + 1 hour', '/some/dir')
