The original idea was to have a daemon that wakes up every minute, scans +a set of files under a special directory, and determines from those files if +any shell commands should be executed in this minute. + +The new idea is to read the required command instructions, work out which +command needs to be executed next, and then sleep until the inferred time has +arrived. On waking the commands are run, and the time of the next command is +computed. Furthermore, the specifications are written in scheme, allowing at +the same time simple command execution instructions and very much more flexible +ones to be composed than the original Vixie format. This has several useful +advantages over the original idea. + +WWW: http://rdmp.org/mcron/ |
