无法理解命令查找的语法 [英] Unable to understand the syntax of the command find

问题描述

find命令与其他Unix命令似乎不同。

为什么在下面的命令末尾会出现空的大括号和反向的闪烁？

  find * -perm 777 -exec chmod 770 {} \; 
  

我找到大括号的原因之一，但不是反向闪存。

大括号显然是路径

与-exec相同，不同之处在于``{}''被
替换为每个
实用程序的
可能的路径名称

解决方案

我建议您改为

 找 。 -perm 777 -print0 | xargs -0 chmod 770 
  

xargs表示将查找的结果一段时间到下面的命令。

The find command seems to differ from other Unix commands.

Why is there the empty curly brackets and a backward flash at the end of the following command?

find * -perm 777 -exec chmod 770 {} \;

I found one reason for the curly brackets but not for the backward flash.

The curly brackets are apparently for the path

Same as -exec, except that ``{}'' is replaced with as many pathnames as possible for each invocation of utility

解决方案

I'd recommend that you instead do that as

find . -perm 777 -print0 | xargs -0 chmod 770

"xargs" says to take the results of the find and feed it 20 at a time to the following command.
