# 删除 untracked files

git clean -f

# 连 untracked 的目录也一起删掉

git clean -fd

# 连 gitignore 的untrack 文件/目录也一起删掉 （慎用，一般这个是用来删掉编译出来的 .o之类的文件用的）

git clean -xfd

# 在用上述 git clean 前，墙裂建议加上 -n 参数来先看看会删掉哪些文件，防止重要文件被误删

NAME

       git-clean - Remove untracked files from the working tree

SYNOPSIS

       git clean [-d] [-f] [-i] [-n] [-q] [-e <pattern>] [-x | -X] [--] <path>...

DESCRIPTION

       Cleans the working tree by recursively removing files that are not under version control, starting from the current directory.

       Normally, only files unknown to Git are removed, but if the -x option is specified, ignored files are also removed. This can, for example, be useful to remove all build products.

       If any optional <path>... arguments are given, only those paths are affected.

usage: git clean [-d] [-f] [-i] [-n] [-q] [-e <pattern>] [-x | -X] [--] <paths>...

    -q, --quiet           do not print names of files removed

    -n, --dry-run         dry run

    -f, --force           force

    -i, --interactive     interactive cleaning

    -d                    remove whole directories

    -e, --exclude <pattern>

                          add <pattern> to ignore rules

    -x                    remove ignored files, too

    -X                    remove only ignored files
