@w4mxl launcher 需要单独安装？？

git update-index

--[no-]assume-unchanged
When this flag is specified, the object names recorded for the paths
are not updated. Instead, this option sets/unsets the "assume
unchanged" bit for the paths. When the "assume unchanged" bit is on,
the user promises not to change the file and allows Git to assume that
the working tree file matches what is recorded in the index. If you
want to change the working tree file, you need to unset the bit to
tell Git. This is sometimes helpful when working with a big project on
a filesystem that has very slow lstat(2) system call (e.g. cifs).

Git will fail (gracefully) in case it needs to modify this file in the
index e.g. when merging in a commit; thus, in case the
assumed-untracked file is changed upstream, you will need to handle
the situation manually.
