SYNOPSIS
git update-index [options] [files...]
DESCRIPTION
git update-index registers file contents in the working tree to the index. It is a low-level plumbing command used internally by `git add`.The most common use is the `--assume-unchanged` flag, which tells Git to temporarily ignore changes to a tracked file. The `--skip-worktree` flag serves a similar purpose but is intended for files managed by sparse checkout.
PARAMETERS
--assume-unchanged
Ignore changes to file.--no-assume-unchanged
Track changes again.--skip-worktree
Skip worktree bit.--no-skip-worktree
Clear skip-worktree.--add
Add file to index.--remove
Remove file from index.--refresh
Refresh stat info; errors on paths that need updating unless -q is given.-q
Used with --refresh: continue quietly even if paths need updating, instead of erroring out.--really-refresh
Like --refresh, but check stat information unconditionally, ignoring the assume-unchanged bit.--chmod=(+|-)x
Set or unset the executable bit for updated paths.--stdin
Read list of paths from standard input instead of the command line, one per line (or NUL-separated with -z).--index-info
Read index entries (mode, object, path) from standard input to add, replace, or remove entries directly.--cacheinfo mode,object,path
Directly insert an entry into the index without needing a corresponding file in the working tree.-z
Use NUL as the line terminator with --stdin or --index-info.--ignore-submodules
Skip submodule checks when used with --refresh.--split-index, --no-split-index
Enable or disable the split-index feature for large repositories.--untracked-cache, --no-untracked-cache
Enable or disable caching of untracked file information to speed up git status.
