在目录的所有文件名中查找并替换另一个单词 [英] find and replace a word with another in all file names of a directory

问题描述

我尝试在我的目录（以及所有子目录）的所有文件名中将owner替换为user。

例

  owners_controller => users_controller 
 owner.rb => user.rb 
  

任何帮助将不胜感激

find 与 -exec 选项调用在其名称中包含 owner 的每个文件和子目录中重命名：

  find path / to / my / directory / -depth -name* owner *-exec / usr / bin / rename owner user {} \ + 
  

如果您没有 rename ，您可以使用 mv 命令与 bash 参数展开：

  find / old /{}; new =$ {old＃} / ＃* /}; echo$ {old％/ *} / $ {new / owner / user}）'\; 
  

bash -c'...'在由单引号括起来的单行程中调用bash shell。单线程用作 mv 命令，该命令将匹配的文件名/子目录的基本名称中的所有 owner 重命名为用户。

具体来说， find 替换每个 {} / code>后面的 -exec 与匹配的文件/子目录的路径名。这里 mv 接受两个参数;第一个是 {} （如前所述），第二个是从子shell $（...）包含三个bash命令。这些bash命令使用参数扩展技术进行重命名基本名称 {} 。

I'm trying to replace the word "owner" with "user" in all file names of my directory (and in all subdirectories).

Ex.

owners_controller => users_controller
owner.rb => user.rb

Any help would be appreciated

解决方案

Use find with the -exec option to call rename on every file and subdirectory containing "owner" in its name:

find path/to/my/directory/ -depth -name "*owner*" -exec /usr/bin/rename owner user {} \+

If you don't have rename, you can use a mv command with bash parameter expansion:

find path/to/my/directory/ -depth -name "*owner*" -exec \
  bash -c 'mv "{}" $(old="{}"; new="${old##*/}"; echo "${old%/*}/${new/owner/user}")' \;

bash -c '...' invokes the bash shell on the one-liner surrounded by single-quotes. The one-liner acts as a mv command that renames all occurrences of "owner" in the basename of the matching filename/subdirectory to "user".

Specifically, find substitutes every {} after the -exec with the matching file/subdirectory's pathname. Here mv accepts two arguments; the first is {} (described previously), and the second is a string returned from a sub-shell $(...) containing three bash commands. These bash commands use parameter expansion techniques to rename the basename of {}.
