在哪里我把我原来并不重要(但它是在 $ HOME /等
,因为它发生源控制之下)。该系统具有自己的地方需要它的文件副本。
Where I keep my original is immaterial (but it is under source control in $HOME/etc
as it happens). The system has its own copy of the file where it needs it.
如果您尝试手动放置这些文件,你会被咬伤。也许工作,但话又说回来,它可能不是(它可能在未来改变)。我不会被播放使用非犹太命令其他存储使用crontab文件的冒险游戏的crontab
。
If you try placing the files manually, you will get bitten. It might work, but then again, it might not (and it might change in the future). I wouldn't play the risky game of using other than the kosher command to store crontab files for use by crontab
.
