DESCRIPTION

Modifies the index or directory cache. Each file mentioned is updated

+into the index and any 'unmerged' or 'needs updating' state is
cleared.
The way "git-update-index" handles files it is told about can be modified
OPTIONS
-------
--add::
- If a specified file isn't in the cache already then it's
+ If a specified file isn't in the index already then it's
added.
Default behaviour is to ignore new files.
--remove::
- If a specified file is in the cache but is missing then it's
+ If a specified file is in the index but is missing then it's
removed.
Default behaviour is to ignore removed file.
--refresh::
- Looks at the current cache and checks to see if merges or
+ Looks at the current index and checks to see if merges or
updates are needed by checking stat() information.
+-q::
+ Quiet. If --refresh finds that the index needs an update, the
+ default behavior is to error out. This option makes
+ git-update-index continue anyway.
+
+--unmerged::
+ If --refresh finds unmerged changes in the index, the default
+ behavior is to error out. This option makes git-update-index
+ continue anyway.
+
--ignore-missing::
Ignores missing files during a --refresh
--cacheinfo <mode> <object> <path>::
- Directly insert the specified info into the cache.
+ Directly insert the specified info into the index.
+--index-info::
+ Read index information from stdin.
+
+--chmod=(+|-)x::
+ Set the execute permissions on the updated files.
+
--info-only::
Do not create objects in the object database for all
<file> arguments that follow this flag; just insert
- their object IDs into the cache.
+ their object IDs into the index.
--force-remove::
Remove the file from the index even when the working directory
read list of paths from the standard input. Paths are
separated by LF (i.e. one path per line) by default.
+--verbose::
+ Report what is being added and removed from index.
+
-z::
Only meaningful with `--stdin`; paths are separated with
NUL character instead of LF.
<file>::
Files to act on.
- Note that files begining with '.' are discarded. This includes
+ Note that files beginning with '.' are discarded. This includes
`./file` and `dir/./file`. If you don't want this, then use
cleaner names.
The same applies to directories ending '/' and paths with '//'

+Configuration
+-------------
+
+The command honors `core.filemode` configuration variable. If
+your repository is on an filesystem whose executable bits are
+unreliable, this should be set to 'false'. This causes the
+command to ignore differences in file modes recorded in the
+index and the file mode on the filesystem if they differ only on
+executable bit. On such an unfortunate filesystem, you may
+need to use `git-update-index --chmod=`.
