Rename files recursively Mac OSX

问题

Attempting to rename a bunch of files.

I can rename any instances of foo with bar in the current directory with:

ls . | awk '{print("mv "$1" "$1)}' | sed 's/foo/bar/2' | /bin/sh

What can I add to make it recursive?

Edit/My solution

I don't know/understand this shell type stuff so I did it with some (pretty dirty) Ruby:

5.times do
  Dir["**/*"].each do |f|
    file_name = File.absolute_path f
    should_rename = file_name.include? "yolo"
    new_file_name = file_name.gsub("yolo", "#{@project_name}")
    File.rename(f, new_file_name) if (should_rename and File.exists? f)
  end
end

This has been asked: Recursive batch rename

With your example, you could go with:

brew install rename
find . -exec rename 's|foo|bar|' {} +

回答2:

The rename utility also provides a syntax that does not require knowledge of regex. Once you have installed the utility

brew install rename

The option -s will replace the first instance of foo by bar:

find . -exec rename -s 'foo' 'bar' {} +

And the option -S will replace all instances:

find . -exec rename -S '_' ' ' {} +

This is really the same solution that Marcel Steinbach provided above, just a different syntax.

The answer to "how do I do X recursively on some file structure" is almost always to use find. In this case maybe also in combination with a for loop. The following example would recursively loop over the files matching the pattern foo in the current directory.

thedir=./
for file in $(find $dir -type f -name foo); do
    # rename $file here
done

Depending on your desired renaming scheme and how you wish to express the renaming, the body of the loop will have different renaming command(s).

Simply renaming every file named foo to bar will result in one file bar and that is not what people usually want. The $file variable contains the relative path to the file, so differents bar's will have different paths.
