git-ls-files(1) - Show information about files in the index and the working tree
-c, --cached
    Show cached files in the output (default)
-d, --deleted
    Show deleted files in the output
-m, --modified
    Show modified files in the output
-o, --others
    Show other (i.e. untracked) files in the output
-i, --ignored
    Show only ignored files in the output. When showing files in the index, print only those matched by
    an exclude pattern. When showing "other" files, show only those matched by an exclude pattern.
-s, --stage
    Show staged contents' object name, mode bits and stage number in the output.
    If a whole directory is classified as "other", show just its name (with a trailing slash) and not its
    whole contents.
    Do not list empty directories. Has no effect without --directory.
-u, --unmerged
    Show unmerged files in the output (forces --stage)
-k, --killed
    Show files on the filesystem that need to be removed due to file/directory conflicts for
    checkout-index to succeed.
    \0 line termination on output.
-x <pattern>, --exclude=<pattern>
    Skip untracked files matching pattern. Note that pattern is a shell wildcard pattern. See EXCLUDE
    PATTERNS below for more information.
-X <file>, --exclude-from=<file>
    Read exclude patterns from <file>; 1 per line.
    Read additional exclude patterns that apply only to the directory and its subdirectories in <file>.
    Add the standard git exclusions: .git/info/exclude, .gitignore in each directory, and the user’s
    global exclusion file.
    If any <file> does not appear in the index, treat this as an error (return 1).
    When using --error-unmatch to expand the user supplied <file> (i.e. path pattern) arguments to paths,
    pretend that paths which were removed in the index since the named <tree-ish> are still present.
    Using this option with -s or -u options does not make any sense.
    This feature is semi-deprecated. For scripting purpose, git-status(1) --porcelain and git-diff-
    files(1) --name-status are almost always superior alternatives, and users should look at git-
    status(1) --short or git-diff(1) --name-status for more user-friendly alternatives.
    Similar to -t, but use lowercase letters for files that are marked as assume unchanged (see git-
    When run from a subdirectory, the command usually outputs paths relative to the current directory.
    This option forces paths to be output relative to the project top directory.
    After each line that describes a file, add more data about its cache entry. This is intended to show
    as much information as possible for manual inspection; the exact format may change at any time.
