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

oh-my-zsh with zsh provides those great aliases via the git plugin. They can be used in bash as well.

gclean='git clean -fd'
gpristine='git reset --hard && git clean -dfx'

• gclean removes untracked directories in addition to untracked files.
• gpristine hard reset the local changes, remove untracked directories, untracked files and don't use the standard ignore rules read from .gitignore (per directory) and $GIT_DIR/info/exclude, but do still use the ignore rules given with -e options. This allows removing all untracked files, including build products. This can be used (possibly in conjunction with git reset) to create a pristine working directory to test a clean build.
