# List files which exist in the working tree and are ignored by this

# repository's own rules: any .gitignore file, plus $GIT_DIR/info/exclude.

#
|
|
# Unlike `git status --ignored`, the global core.excludesfile is not consulted
|
|
# unless --global is given, so the output only contains paths this repository
|
|
# chose to ignore.

#

# Works inside a linked worktree, where .git is a file and info/exclude lives in
|
|
# the common git directory rather than next to the worktree.

# Usage: git-ls-ignored [<options>] [--] [<pathspec>...]
|
|
#
|
|
# -d, --directory list an ignored directory by name instead of its contents
|
|
# -g, --global also apply the global core.excludesfile
