如何从当前目录删除所有文件，包括当前目录？ [英] How to delete all files from current directory including current directory?

问题描述

如何从当前目录中删除所有文件和子目录，包括当前目录？

解决方案

（在大多数情况下应该是安全的）：

  rm -rf  - $（pwd -P） && cd .. 
  

不在bash下，没有GNU工具，我会使用：

  TMP =`pwd -P`&& cd`dirname $ TMP`&&& rm -rf./'basename $ TMP`&&&取消设置TMP 
  

为什么这样更安全：

./ >

• / code>之前的文件名）


• pwd -P 不只是 pwd 在我们不在一个真实的目录，但在一个符号链接指向它。


• （bash版本）：
  
  
  ul>
  
• 结尾处的 cd .. 可以省略，但您将位于不存在的目录中，否则...

EDIT ：如kmkaplan指出的， - 不必要，因为 pwd 返回在UNIX上始终以 / 开头的完整路径名

How can I delete all files and subdirectories from current directory including current directory?

解决方案

Under bash with GNU tools, I would do it like that (should be secure in most cases):

rm -rf -- "$(pwd -P)" && cd ..

not under bash and without GNU tools, I would use:

TMP=`pwd -P` && cd "`dirname $TMP`" && rm -rf "./`basename $TMP`" && unset TMP

why this more secure:

• end the argument list with -- in cases our directory starts with a dash (non-bash: ./ before the filename)
• pwd -P not just pwd in cases where we are not in a real directory but in a symlink pointing to it.
• "s around the argument in cases the directory contains spaces

some random info (bash version):

• the cd .. at the end can be omitted, but you would be in a non-existant directory otherwise...

EDIT: As kmkaplan noted, the -- thing is not necessary, as pwd returns the complete path name which always starts with / on UNIX
