6 git-index-pack - Build pack index file for an existing packed archive
12 'git index-pack' [-v] [-o <index-file>] <pack-file>
13 'git index-pack' --stdin [--fix-thin] [--keep] [-v] [-o <index-file>]
19 Reads a packed archive (.pack) from the specified file, and
20 builds a pack index file (.idx) for it. The packed archive
21 together with the pack index can then be placed in the
22 objects/pack/ directory of a git repository.
28 Be verbose about what is going on, including progress status.
31 Write the generated pack index into the specified
32 file. Without this option the name of pack index
33 file is constructed from the name of packed archive
34 file by replacing .pack with .idx (and the program
35 fails if the name of packed archive does not end
39 When this flag is provided, the pack is read from stdin
40 instead and a copy is then written to <pack-file>. If
41 <pack-file> is not specified, the pack is written to
42 objects/pack/ directory of the current git repository with
43 a default name determined from the pack content. If
44 <pack-file> is not specified consider using --keep to
45 prevent a race condition between this process and
49 It is possible for 'git-pack-objects' to build
50 "thin" pack, which records objects in deltified form based on
51 objects not included in the pack to reduce network traffic.
52 Those objects are expected to be present on the receiving end
53 and they must be included in the pack for that pack to be self
54 contained and indexable. Without this option any attempt to
55 index a thin pack will fail. This option only makes sense in
56 conjunction with --stdin.
59 Before moving the index into its final destination
60 create an empty .keep file for the associated pack file.
61 This option is usually necessary with --stdin to prevent a
62 simultaneous 'git-repack' process from deleting
63 the newly constructed pack and index before refs can be
64 updated to use objects contained in the pack.
67 Like --keep create a .keep file before moving the index into
68 its final destination, but rather than creating an empty file
69 place 'why' followed by an LF into the .keep file. The 'why'
70 message can later be searched for within all .keep files to
71 locate any which have outlived their usefulness.
73 --index-version=<version>[,<offset>]::
74 This is intended to be used by the test suite only. It allows
75 to force the version for the generated pack index, and to force
76 64-bit index entries on objects located above the given offset.
79 Die, if the pack contains broken objects or links.
85 Once the index has been created, the list of object names is sorted
86 and the SHA1 hash of that list is printed to stdout. If --stdin was
87 also used then this is prefixed by either "pack\t", or "keep\t" if a
88 new .keep file was successfully created. This is useful to remove a
89 .keep file used as a lock to prevent the race with 'git-repack'
