6 git-replace - Create, list, delete refs to replace objects
11 'git replace' [-f] <object> <replacement>
12 'git replace' -d <object>...
13 'git replace' -l [<pattern>]
17 Adds a 'replace' reference in `refs/replace/` namespace.
19 The name of the 'replace' reference is the SHA1 of the object that is
20 replaced. The content of the 'replace' reference is the SHA1 of the
23 Unless `-f` is given, the 'replace' reference must not yet exist.
25 Replacement references will be used by default by all Git commands
26 except those doing reachability traversal (prune, pack transfer and
29 It is possible to disable use of replacement references for any
30 command using the `--no-replace-objects` option just after 'git'.
32 For example if commit 'foo' has been replaced by commit 'bar':
34 ------------------------------------------------
35 $ git --no-replace-objects cat-file commit foo
36 ------------------------------------------------
38 shows information about commit 'foo', while:
40 ------------------------------------------------
41 $ git cat-file commit foo
42 ------------------------------------------------
44 shows information about commit 'bar'.
46 The 'GIT_NO_REPLACE_OBJECTS' environment variable can be set to
47 achieve the same effect as the `--no-replace-objects` option.
52 If an existing replace ref for the same object exists, it will
53 be overwritten (instead of failing).
56 Delete existing replace refs for the given objects.
59 List replace refs for objects that match the given pattern (or
60 all if no pattern is given).
61 Typing "git replace" without arguments, also lists all replace
66 Comparing blobs or trees that have been replaced with those that
67 replace them will not work properly. And using `git reset --hard` to
68 go back to a replaced commit will move the branch to the replacement
69 commit instead of the replaced commit.
71 There may be other problems when using 'git rev-list' related to
72 pending objects. And of course things may break if an object of one
73 type is replaced by an object of another type (for example a blob
74 replaced by a commit).
