FileRevisor command line usage

FileRevisor v1.1.0 - Quickly delete directories, rename files or directories, or replace text in files.

Usage:
   filerevisor delete-directory
      --target=<TargetDirectoryPath>
      [--parallel]
      [--skip-files-in-use]
      [--dryrun]
      [--quiet]
   filerevisor rename-files
      --target=<TargetDirectoryPath>
      --from=<FileNameRegex>
      --to=<FileNameRegex>
      [--recurse]
      [--dryrun]
      [--verbose]
   filerevisor rename-directories
      --target=<TargetDirectoryPath>
      --from=<DirectoryNameRegex>
      --to=<DirectoryNameRegex>
      [--recurse]
      [--dryrun]
      [--verbose]
   filerevisor replace-text
      --target=<TargetDirectoryPath>
      --from=<LiteralFileText>
      --to=<ReplacementLiteralFileText>
      [--recurse]
      [--dryrun]
      [--verbose]

FileRevisor program modes

delete-directory

filerevisor delete-directory
   --target=<TargetDirectoryPath>
   [--parallel]
   [--skip-files-in-use]
   [--dryrun]
   [--quiet]

FileRevisor delete-directory mode quickly deletes all files in and below --target=<TargetDirectoryPath>. For extreme directory deletion performance, especially on Windows, specify --parallel to delete subdirectories below TargetDirectoryPath using one thread per subdirectory.

Here is filerevisor delete-directory in action:

rename-files

filerevisor rename-files
   --target=<TargetDirectoryPath>
   --from=<FileNameRegex>
   --to=<FileNameRegex>
   [--recurse]
   [--dryrun]
   [--verbose]

FileRevisor rename-files mode renames files in a specified directory matching a specified regular expression. --recurse can be specified to rename files in and below a specified directory.

Here is filerevisor rename-files in action:

rename-directories

filerevisor rename-directories
   --target=<TargetDirectoryPath>
   --from=<DirectoryNameRegex>
   --to=<DirectoryNameRegex>
   [--recurse]
   [--dryrun]
   [--verbose]

FileRevisor rename-directories mode renames directories in a specified directory matching a specified regular expression. --recurse can be specified to rename directories in and below a specified directory.

Here is filerevisor rename-directories in action:

replace-text

filerevisor replace-text
   --target=<TargetDirectoryPath>
   --from=<LiteralFileText>
   --to=<ReplacementLiteralFileText>
   [--recurse]
   [--dryrun]
   [--verbose]

FileRevisor replace-text mode replaces text in files containing a substring with a replacement substring. --recurse can be added to replace text in files in and below a specified directory.

Here is filerevisor replace-text in action:

Linux FileRevisor parallel directory deletion performance

Windows FileRevisor parallel folder deletion performance

As you can see from the above two graphs, Linux file deletions are quite a bit faster than Windows file deletions, with modest time savings available on Linux and massive time savings available on Windows by way of FileRevisor --parallel directory deletion.

The OS, CPU, and storage hardware which generated the above performance numbers is Fedora 33 / Windows 10, 32-core 64-thread AMD Threadripper 2990WX, and a 512 GB Samsung 970 PRO NVMe drive.

4 steps to build binary filerevisor from source on Linux with Clang

git clone https://github.com/NeilJustice/FileRevisor
cd FileRevisor && mkdir Release && cd Release
CXX=clang++ cmake .. -DCMAKE_BUILD_TYPE=Release
sudo cmake --build . --target install

Resulting binary /usr/local/bin/filerevisor:

4 steps to build executable FileRevisor.exe from source on Windows with Visual Studio 2022
