- Compare files (lists changes to turn `old_file` into `new_file`):
|
|
|
|
`diff {{old_file}} {{new_file}}`
|
|
|
|
- Compare files, ignoring white spaces:
|
|
|
|
`diff -w {{old_file}} {{new_file}}`
|
|
|
|
- Compare files, showing the differences side by side:
|
|
|
|
`diff -y {{old_file}} {{new_file}}`
|
|
|
|
- Compare files, showing the differences in unified format (as used by `git diff`):
|
|
|
|
`diff -u {{old_file}} {{new_file}}`
|
|
|
|
- Compare directories recursively (shows names for differing files/directories as well as changes made to files):
|
|
|
|
`diff -r {{old_directory}} {{new_directory}}`
|
|
|
|
- Compare directories, only showing the names of files that differ:
|
|
|
|
`diff -rq {{old_directory}} {{new_directory}}`
|
