为什么这个正则表达式不起作用： find ./ -regex '.[mh]$' |排序| grep --exclude="UnitTests"

为什么这个正则表达式不起作用：

   find ./ -regex '.*[mh]$' | sort | grep --exclude="UnitTests" *

以下有效：

   find ./ -regex '.*[mh]$' | sort
   find ./ -regex '.*[mh]$' | sort | grep "UnitTests"

当我添加“--exclude”时（因为我想要除其中包含 UnitTests 的行之外的所有内容），我似乎感到悲伤。

原文

why isn't this regex working:

   find ./ -regex '.*[mh]
The following works:
   find ./ -regex '.*[mh]
When I'm adding the "--exclude" (as I want everything but lines with UnitTests in them) I seem to come to grief.  
I'm on Mac OSX
 | sort | grep --exclude="UnitTests" *

The following works:

代替使用

find ./ -regex '.*[mh]
。 --exclude 在递归子目录时使用，但您的 grep 是基于 find ./ -regex '.*[mh 的管道（输出）完成的]$'|排序。
 | sort | grep -v "UnitTests"

。 --exclude 在递归子目录时使用，但您的 grep 是基于 find ./ -regex '.*[mh 的管道（输出）完成的]$'|排序。

Use

find ./ -regex '.*[mh]
instead. --exclude is used when recursing subdirectories, but your grep is done based on the pipe (the output) from find ./ -regex '.*[mh]$' | sort.
 | sort | grep -v "UnitTests"

instead. --exclude is used when recursing subdirectories, but your grep is done based on the pipe (the output) from find ./ -regex '.*[mh]$' | sort.
