+It is possible to print in a custom format by using the `--format`
+option, which is able to interpolate different fields using
+a `%(fieldname)` notation. For example, if you only care about the
+"objectname" and "path" fields, you can execute with a specific
+"--format" like
+
+ git ls-files --format='%(objectname) %(path)'
+
+FIELD NAMES
+-----------
+The way each path is shown can be customized by using the
+`--format=<format>` option, where the %(fieldname) in the
+<format> string for various aspects of the index entry are
+interpolated. The following "fieldname" are understood:
+
+objectmode::
+ The mode of the file which is recorded in the index.
+objectname::
+ The name of the file which is recorded in the index.
+stage::
+ The stage of the file which is recorded in the index.
+eolinfo:index::
+eolinfo:worktree::
+ The <eolinfo> (see the description of the `--eol` option) of
+ the contents in the index or in the worktree for the path.
+eolattr::
+ The <eolattr> (see the description of the `--eol` option)
+ that applies to the path.
+path::
+ The pathname of the file which is recorded in the index.
