Linux下快速删除大量文件
方法见下:
1)首先建立一个空白文件夹。
mkdir /tmp/empty
2)之后使用以下语句即可快速的删除文件。
rsync --delete-before -d /tmp/empty/ /the/folder/you/want/delete/
z注意:不要忘记文件夹后的"/"
?
rsync提供了一些跟删除相关的参数?
rsync --help | grep delete?
???? --del?????????????????? an alias for --delete-during?
???? --delete??????????????? delete files that don‘t exist on the sending side?
???? --delete-before???????? receiver deletes before transfer (default)?
???? --delete-during???????? receiver deletes during transfer, not before?
???? --delete-after????????? receiver deletes after transfer, not before?
???? --delete-excluded?????? also delete excluded files on the receiving side?
???? --ignore-errors???????? delete even if there are I/O errors?
???? --max-delete=NUM??????? don‘t delete more than NUM files?
?
rsync --delete-before -a -H -v --progress --stats /tmp/test/ log/
这样我们要删除的log目录就会被清空了,删除的速度会非常快。rsync实际上用的是替换原理,处理数十万个文件也是秒删。
选项说明:
–delete-before 接收者在传输之前进行删除操作
–progress 在传输时显示传输过程
-a 归档模式,表示以递归方式传输文件,并保持所有文件属性
-H 保持硬连接的文件
-v 详细输出模式
–stats 给出某些文件的传输状态
