hackdorte@20007 | 1 Anacron is a periodic command scheduler. It executes commands at intervals |
hackdorte@20007 | 2 specified in days. Unlike cron, it does not assume that the system is running |
hackdorte@20007 | 3 continuously. It can therefore be used to control the execution of daily, |
hackdorte@20007 | 4 weekly and monthly jobs (or anything with a period of n days), on systems |
hackdorte@20007 | 5 that don't run 24 hours a day. When installed and configured properly, |
hackdorte@20007 | 6 Anacron will make sure that the commands are run at the specified intervals |
hackdorte@20007 | 7 as closely as machine-uptime permits. |
hackdorte@20007 | 8 |
hackdorte@20007 | 9 Every time Anacron is run, it reads a configuration file that specifies the |
hackdorte@20007 | 10 jobs Anacron controls, and their periods in days. If a job wasn't executed in |
hackdorte@20007 | 11 the last n days, where n is the period of that job, Anacron executes it. |
hackdorte@20007 | 12 Anacron then records the date in a special timestamp file that it keeps for |
hackdorte@20007 | 13 each job, so it can know when to run it again. When all the executed commands |
hackdorte@20007 | 14 terminate, Anacron exits. |
