在目录的所有文件名中查找单词并将其替换为另一个单词 [英] find and replace a word with another in all file names of a directory

问题描述

我正在尝试将我的目录(以及所有子目录)的所有文件名中的所有者"一词替换为用户".

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

例如

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

任何帮助将不胜感激

推荐答案

使用 find 和 -exec 选项来调用 rename名称中包含owner"的文件和子目录:

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 {} +

如果你没有rename，你可以使用带有bash参数扩展的mv命令:

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 '...' 在单引号包围的单行上调用 bash shell.单行作为 mv 命令，将匹配文件名/子目录的基本名称中所有出现的owner"重命名为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".

具体来说，find 将 -exec 之后的每个 {} 替换为匹配的文件/子目录的路径名.这里 mv 接受两个参数；第一个是 {}(之前描述过)，第二个是从包含三个 bash 命令的子 shell $(...) 返回的字符串.这些 bash 命令使用参数扩展技术来重命名{} 的基本名称.

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 {}.
