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
|
|
using the various options:
|
|
|
|
OPTIONS
|
|
-------
|
|
--add::
|
|
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 index but is missing then it's
|
|
removed.
|
|
Default behaviour is to ignore removed file.
|
|
|
|
--refresh::
|
|
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 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 index.
|
|
|
|
--force-remove::
|
|
Remove the file from the index even when the working directory
|
|
still has such a file. (Implies --remove.)
|
|
|
|
--replace::
|
|
By default, when a file `path` exists in the index,
|
|
git-update-index refuses an attempt to add `path/file`.
|
|
Similarly if a file `path/file` exists, a file `path`
|
|
cannot be added. With --replace flag, existing entries
|
|
that conflicts with the entry being added are
|
|
automatically removed with warning messages.
|
|
|
|
--stdin::
|
|
Instead of taking list of paths from the command line,
|
|
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.
|
|
|
|
--::
|
|
Do not interpret any more arguments as options.
|
|
|
|
<file>::
|
|
Files to act on.
|
|
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 '//'
|
|
|
|
Using --refresh
|
|
---------------
|
|
'--refresh' does not calculate a new sha1 file or bring the index
|
|
up-to-date for mode/content changes. But what it *does* do is to
|
|
"re-match" the stat information of a file with the index, so that you
|
|
can refresh the index for a file that hasn't been changed but where
|
|
the stat entry is out of date.
|
|
|
|
For example, you'd want to do this after doing a "git-read-tree", to link
|
|
up the stat index details with the proper files.
|
|
|
|
Using --cacheinfo or --info-only
|
|
--------------------------------
|
|
'--cacheinfo' is used to register a file that is not in the
|
|
current working directory. This is useful for minimum-checkout
|
|
merging.
|
|
|
|
To pretend you have a file with mode and sha1 at path, say:
|
|
|
|
$ git-update-index --cacheinfo mode sha1 path
|
|
|
|
'--info-only' is used to register files without placing them in the object
|
|
database. This is useful for status-only repositories.
|
|
|
|
Both '--cacheinfo' and '--info-only' behave similarly: the index is updated
|
|
but the object database isn't. '--cacheinfo' is useful when the object is
|
|
in the database but the file isn't available locally. '--info-only' is
|
|
useful when the file is available, but you do not wish to update the
|
|
object database.
|
|
|
|
Examples
|
|
--------
|
|
To update and refresh only the files already checked out:
|
|
|
|
git-checkout-index -n -f -a && git-update-index --ignore-missing --refresh
|
|
|
|
|
|
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=`.
