git-replace(1)

NAME
|
|
----
|
|
git-replace - Create, list, delete refs to replace objects
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git replace' [-f] <object> <replacement>
|
|
'git replace' -d <object>...
|
|
'git replace' -l [<pattern>]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Adds a 'replace' reference in `refs/replace/` namespace.
|
|
|
|
The name of the 'replace' reference is the SHA-1 of the object that is
|
|
replaced. The content of the 'replace' reference is the SHA-1 of the
|
|
replacement object.
|
|
|
|
Unless `-f` is given, the 'replace' reference must not yet exist.
|
|
|
|
Replacement references will be used by default by all Git commands
|
|
except those doing reachability traversal (prune, pack transfer and
|
|
fsck).
|
|
|
|
It is possible to disable use of replacement references for any
|
|
command using the `--no-replace-objects` option just after 'git'.
|
|
|
|
For example if commit 'foo' has been replaced by commit 'bar':
|
|
|
|
------------------------------------------------
|
|
$ git --no-replace-objects cat-file commit foo
|
|
------------------------------------------------
|
|
|
|
shows information about commit 'foo', while:
|
|
|
|
------------------------------------------------
|
|
$ git cat-file commit foo
|
|
------------------------------------------------
|
|
|
|
shows information about commit 'bar'.
|
|
|
|
The 'GIT_NO_REPLACE_OBJECTS' environment variable can be set to
|
|
achieve the same effect as the `--no-replace-objects` option.
|
|
|
|
OPTIONS
|
|
-------
|
|
-f::
|
|
If an existing replace ref for the same object exists, it will
|
|
be overwritten (instead of failing).
|
|
|
|
-d::
|
|
Delete existing replace refs for the given objects.
|
|
|
|
-l <pattern>::
|
|
List replace refs for objects that match the given pattern (or
|
|
all if no pattern is given).
|
|
Typing "git replace" without arguments, also lists all replace
|
|
refs.
|
|
|
|
BUGS
|
|
----
|
|
Comparing blobs or trees that have been replaced with those that
|
|
replace them will not work properly. And using `git reset --hard` to
|
|
go back to a replaced commit will move the branch to the replacement
|
|
commit instead of the replaced commit.
|
|
|
|
There may be other problems when using 'git rev-list' related to
|
|
pending objects. And of course things may break if an object of one
|
|
type is replaced by an object of another type (for example a blob
|
|
replaced by a commit).
