How to remove local (untracked) files from the current Git working tree

Question

How do you delete untracked local files from your current working tree?

Answer 1

User interactive approach:

git clean -i -fd

Remove .classpath [y/N]? N
Remove .gitignore [y/N]? N
Remove .project [y/N]? N
Remove .settings/ [y/N]? N
Remove src/com/arsdumpgenerator/inspector/ [y/N]? y
Remove src/com/arsdumpgenerator/manifest/ [y/N]? y
Remove src/com/arsdumpgenerator/s3/ [y/N]? y
Remove tst/com/arsdumpgenerator/manifest/ [y/N]? y
Remove tst/com/arsdumpgenerator/s3/ [y/N]? y

-i for interactive
-f for force
-d for directory
-x for ignored files(add if required)

Note: Add -n or --dry-run to just check what it will do.
