[SOLVED] Replace the occurrences in file name, folder name and file content

Issue

I have folders and files with the following structure and some of the files contains the string ModuleName.

ModuleName
├── Application\ Logic
│   └── Interactor
│       ├── ModuleNameInteractor.swift
│       └── ModuleNameInteractorIO.swift
├── Module\ Interface
│   └── IModuleNameModule.swift
└── User\ Interface
    ├── Presenter
    │   └── ModuleNamePresenter.swift
    ├── View
    │   ├── IModuleNameView.swift
    │   └── ModuleNameViewController.swift
    └── Wireframe
        └── ModuleNameWireframe.swift

I want to replace all the occurrences of ModuleName in folder name, file name and file content by another name (let's say TestModule) with a Linux or a python script.

I tried with the find command but renaming the folders provoque No such file or directory for the subfolders / subfiles.


Solution

I'd use sed -i (in-place replace) for the content replacements, and a find|while read loop for the renames.

Here's the BSD sed (standard on Macs) version:

find . -type f -exec sed -e s/ModuleName/TestModule/g -i '' '{}' ';'
find . -depth -name '*ModuleName*' -print0|while IFS= read -rd '' f; do mv -i "$f" "$(echo "$f"|sed -E 's/(.*)ModuleName/\1TestModule/')"; done

And here's GNU sed:

find . -type f -exec sed -e s/ModuleName/TestModule/g -i '{}' ';'
find . -depth -name '*ModuleName*' -print0|while IFS= read -rd '' f; do mv -i "$f" "$(echo "$f"|sed -r 's/(.*)ModuleName/\1TestModule/')"; done

The extra details in the while read are to correctly handle arbitrary filenames -- names with spaces and other odd characters. Some quick testing suggests that zsh read can now handle null-terminated strings properly; if you have issues, try running it in bash instead.
