6 git-pack-objects - Create a packed archive of objects.
11 'git-pack-objects' [--non-empty] [--local] [--incremental] [--window=N] [--depth=N] {--stdout | base-name} < object-list
16 Reads list of objects from the standard input, and writes a packed
17 archive with specified base-name, or to the standard output.
19 A packed archive is an efficient way to transfer set of objects
20 between two repositories, and also is an archival format which
21 is efficient to access. The packed archive format (.pack) is
22 designed to be unpackable without having anything else, but for
23 random access, accompanied with the pack index file (.idx).
25 'git-unpack-objects' command can read the packed archive and
26 expand the objects contained in the pack into "one-file
27 one-object" format; this is typically done by the smart-pull
28 commands when a pack is created on-the-fly for efficient network
29 transport by their peers.
31 Placing both in the pack/ subdirectory of $GIT_OBJECT_DIRECTORY (or
32 any of the directories on $GIT_ALTERNATE_OBJECT_DIRECTORIES)
33 enables git to read from such an archive.
39 Write into a pair of files (.pack and .idx), using
40 <base-name> to determine the name of the created file.
41 When this option is used, the two files are written in
42 <base-name>-<SHA1>.{pack,idx} files. <SHA1> is a hash
43 of object names (currently in random order so it does
44 not have any useful meaning) to make the resulting
45 filename reasonably unique, and written to the standard
46 output of the command.
49 Write the pack contents (what would have been writtin to
50 .pack file) out to the standard output.
52 --window and --depth::
53 These two options affects how the objects contained in
54 the pack are stored using delta compression. The
55 objects are first internally sorted by type, size and
56 optionally names and compared against the other objects
57 within --window to see if using delta compression saves
58 space. --depth limits the maximum delta depth; making
59 it too deep affects the performance on the unpacker
60 side, because delta data needs to be applied that many
61 times to get to the necessary object.
64 This flag causes an object already in a pack ignored
65 even if it appears in the standard input.
68 This flag is similar to `--incremental`; instead of
69 ignoring all packed objects, it only ignores objects
70 that are packed and not in the local object store
71 (i.e. borrowed from an alternate).
