Linux命令输出作为另一个命令的参数 [英] Linux command output as a parameter of another command

问题描述

我想传递命令的元素的输出列表作为另一个命令的参数。我找到了一些其他页面：

• 如何在stdout上显示Linux命令的输出并将其传递给另一个命令？


• 使用bash命令的输出（带管道）作为另一个命令的参数

我只想将一个文件复制到调用Linux的每个结果 find 命令。

这里有什么问题？：

  find。 -name myFile 2>& 1 | cp / home / myuser / myFile $ 1 
  

感谢

解决方案

这是你想要的：

  -name myFile -exec cp / home / myuser / myFile {}';'
  

细目/解释

• find ：调用find命令
$ b

• 由于没有指定深度标记，因此将递归搜索所有子文件夹


• -name myFile ：查找显式名为的文件myFile


• -exec ：对于搜索结果，请执行其他命令


• cp / home / myuser / myFile {} ：copies / home / myuser / myFile 覆盖 find to; $ { {} 。


• ';'：用于分隔要在之后运行的不同命令

I would like to pass the output list of elements of a command as a parameter of another command. I have found some other pages:

• How to display the output of a Linux command on stdout and also pipe it to another command?
• Use output of bash command (with pipe) as a parameter for another command

but they seem to be more complex.

I just would like to copy a file to every result of a call to the Linux find command.

What is wrong here?:

find . -name myFile 2>&1 | cp /home/myuser/myFile $1

Thanks

解决方案

This is what you want:

find . -name myFile -exec cp /home/myuser/myFile {} ';'

A breakdown / explanation of this:

• find: invoking the find command
• .: start search from current working directory.
• Since no depth flags are specified, this will search recursively for all subfolders
• -name myFile: find files with the explicit name myFile
• -exec: for the search results, perform additional commands with them
• cp /home/myuser/myFile {}: copies /home/myuser/myFile to overwrite each result returned by find to ; think of {} as where each search result goes.
• ';': used to separate different commands to be run after find
