6 git-index-pack - Build pack index file for an existing packed archive
7
9 git index-pack [-v] [-o <index-file>] <pack-file>
10 git index-pack --stdin [--fix-thin] [--keep] [-v] [-o <index-file>]
11 [<pack-file>]
12
15 Reads a packed archive (.pack) from the specified file, and builds a
16 pack index file (.idx) for it. The packed archive together with the
17 pack index can then be placed in the objects/pack/ directory of a git
18 repository.
19
21 -v
22 Be verbose about what is going on, including progress status.
23 -o <index-file>
25 Write the generated pack index into the specified file. Without
26 this option the name of pack index file is constructed from the
27 name of packed archive file by replacing .pack with .idx (and the
28 program fails if the name of packed archive does not end with
29 .pack).
30 --stdin
32 When this flag is provided, the pack is read from stdin instead and
33 a copy is then written to <pack-file>. If <pack-file> is not
34 specified, the pack is written to objects/pack/ directory of the
35 current git repository with a default name determined from the pack
36 content. If <pack-file> is not specified consider using --keep to
37 prevent a race condition between this process and git repack.
38 --fix-thin
40 Fix a "thin" pack produced by git pack-objects --thin (see git-
41 pack-objects(1) for details) by adding the excluded objects the
42 deltified objects are based on to the pack. This option only makes
43 sense in conjunction with --stdin.
44 --keep
46 Before moving the index into its final destination create an empty
47 .keep file for the associated pack file. This option is usually
48 necessary with --stdin to prevent a simultaneous git repack process
49 from deleting the newly constructed pack and index before refs can
50 be updated to use objects contained in the pack.
51 --keep=why
53 Like --keep create a .keep file before moving the index into its
54 final destination, but rather than creating an empty file place why
55 followed by an LF into the .keep file. The why message can later be
56 searched for within all .keep files to locate any which have
57 outlived their usefulness.
58 --index-version=<version>[,<offset>]
60 This is intended to be used by the test suite only. It allows to
61 force the version for the generated pack index, and to force 64-bit
62 index entries on objects located above the given offset.
63 --strict
65 Die, if the pack contains broken objects or links.
66
68 Once the index has been created, the list of object names is sorted and
69 the SHA1 hash of that list is printed to stdout. If --stdin was also
70 used then this is prefixed by either "pack\t", or "keep\t" if a new
71 .keep file was successfully created. This is useful to remove a .keep
72 file used as a lock to prevent the race with git repack mentioned
73 above.
