查找扩展名为5个或更多字符的文件 [英] Find files with extension with 5 characters or more

问题描述

我有很多来自失败的rsync命令的残留文件。他们都有一个5（随机）字符的文件扩展名。有一个命令，可以找到扩展名为4个字符和更多递归的所有文件？

一个rsync残留文件名的例子：foo.jpg.hzmkjt7

我已经找到了一种防止rsync的方法，但我现在要做的就是清理那些剩下的东西...

globstar 像这样：

  shopt -s globstar＃启用shell选项
 echo ** / *。 ＃来测试哪些文件匹配
 rm ** / *。 ＃如果您满意的话
  

该模式匹配当前目录中的任何文件或任何结尾的子目录一个。后跟5个字符。

与 code>？，你可以通过更改glob使其更类似于 ** / *。[[：alnum：]] [[：alnum：] ] [[：alnum：]] [[：alnum：]] [[：alnum：]] 以匹配5个字母数字字符。

I have a lot of residue files from a failed rsync-command. They all have a file extension of 5 (random)characters. Is there a command that can find all files with an extension of 4 characters and more recursively?

Example of a rsync residue filename: foo.jpg.hzmkjt7

I've already found out a way to prevent this with rsync, but all I need to do now is clean those leftovers...

解决方案

Using bash, one option would be to use globstar like this:

shopt -s globstar # enable the shell option
echo **/*.?????   # to test which files are matched
rm **/*.?????     # if you're happy

The pattern matches any files in the current directory or any subdirectories that end in a . followed by 5 characters.

Rather than matching any character with a ?, you could go more specific by changing the glob to something like **/*.[[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]][[:alnum:]] to match 5 alphanumeric characters.
