我正在寻找一个将保留最后10个版本(子文件夹)并删除其余版本的命令.

I'm looking for a command that will leave the last 10 versions (sub-folders) and deletes the rest.

有什么想法吗?

推荐答案

您去了.(已编辑)

ls -dt */|尾-n +11 |xargs rm -rf

首先列出最近修改过的目录，然后将除前10个目录之外的所有目录都保存下来，然后将它们发送到 rm -rf .

First list directories recently modified then take all of them except first 10, then send them to rm -rf.
