Using find to delete all subdirectories (and their files)
提问by infmz
I'm sure this is straight forward and answered somewhere, but I didn't manage to find what I was looking for. Basically, I'm trying to run a cron script to clear the contents of a given directory every 7 days. So far I have tried the following,
我确定这是直截了当的并在某处回答，但我没能找到我想要的东西。基本上，我试图运行一个 cron 脚本来每 7 天清除一次给定目录的内容。到目前为止，我已经尝试了以下，
find /myDir -mtime 7 -exec rm -rf {} \;
This however also deletes the parent directory myDir, which I do not want. I also tried,
但是，这也会删除我不想要的父目录 myDir。我也试过，
find /myDir -type f -type d -mtime 7 -delete
which appeared to do nothing. I also tried,
这似乎什么也没做。我也试过，
fnd /myDir -type d -delete
which deleted all but the parent directory just as I need. However, a warning message came up reading,
根据我的需要删除了除父目录之外的所有目录。然而，一条警告信息出现了，
relative path potentially not safe
相对路径可能不安全
I'd appreciate if anyone can rectify my script so that it safely deletes all subdirectories in folder.
如果有人可以纠正我的脚本，以便它安全地删除文件夹中的所有子目录，我将不胜感激。
Many thanks. =)
非常感谢。=)
UPDATE:I decided to go for the following,
更新：我决定进行以下操作，
find /myDir -mindepth 1 -mtime 7 -delete
Based upon what I learned from all who replied. Again, many thanks to you all.
根据我从所有回复的人那里学到的。再次，非常感谢你们所有人。

What about
关于什么
cd myDir/ ; find . -type d -delete
assuming that you run this from myDirparent directory.
假设您从myDir父目录运行它。
If you can't guarantee myDir exists, then this is safer:
如果你不能保证 myDir 存在，那么这更安全：
cd myDir/ && find . -type d -delete
回答by Bobby Impollonia
find /myDir -mindepth 1 -mtime 7 -delete
find /myDir -mindepth 1 -mtime 7 -delete
should probably be
应该是
find /myDir -mindepth 1 -mtime +7 -delete
find /myDir -mindepth 1 -mtime +7 -delete
(or maybe mtime +6). The +means things 7 days old or older rather than exactly 7 days.
（或者也许mtime +6）。这+意味着 7 天或更早的事情，而不是 7 天。
