Compare files and directories. More information: <https://man7.org/linux/man-pages/man1/diff.1.html>.

  • Compare files (lists changes to turn `old_file` into `new_file`):
    diff old_file new_file
  • Compare files, ignoring white spaces:
    diff --ignore-all-space old_file new_file
  • Compare files, showing the differences side by side:
    diff --side-by-side old_file new_file
  • Compare files, showing the differences in unified format (as used by `git diff`):
    diff --unified old_file new_file
  • Compare directories recursively (shows names for differing files/directories as well as changes made to files):
    diff --recursive old_directory new_directory
  • Compare directories, only showing the names of files that differ:
    diff --recursive --brief old_directory new_directory
  • Create a patch file for Git from the differences of two text files, treating nonexistent files as empty:
    diff --text --unified --new-file old_file new_file > diff.patch
