+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
+-----------
+Various values from structured fields can be used to interpolate
+into the resulting output. For each outputting line, the following
+names can be used:
+
+tag::
+ The tag of file status.
+objectmode::
+ The mode of the object.
+objectname::
+ The name of the object.
+stage::
+ The stage of the file.
+eol::
+ The line endings of files.
+path::
+ The pathname of the object.
+ctime::
+ The create time of file.
+mtime::
+ The modify time of file.
+dev::
+ The ID of device containing file.
+ino::
+ The inode number of file.
+uid::
+ The user id of file owner.
+gid::
+ The group id of file owner.
+size::
+ The size of the file.
+flags::
+ The flags of the file.
