1git-index-pack(1) 2================= 3 4NAME 5---- 6git-index-pack - Build pack index file for an existing packed archive 7 8 9SYNOPSIS 10-------- 11[verse] 12'git index-pack' [-v] [-o <index-file>] <pack-file> 13'git index-pack' --stdin [--fix-thin] [--keep] [-v] [-o <index-file>] 14 [<pack-file>] 15 16 17DESCRIPTION 18----------- 19Reads a packed archive (.pack) from the specified file, and 20builds a pack index file (.idx) for it. The packed archive 21together with the pack index can then be placed in the 22objects/pack/ directory of a git repository. 23 24 25OPTIONS 26------- 27-v:: 28 Be verbose about what is going on, including progress status. 29 30-o <index-file>:: 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 36 with .pack). 37 38--stdin:: 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 46 'git repack'. 47 48--fix-thin:: 49 Fix a "thin" pack produced by `git pack-objects --thin` (see 50 linkgit:git-pack-objects[1] for details) by adding the 51 excluded objects the deltified objects are based on to the 52 pack. This option only makes sense in conjunction with --stdin. 53 54--keep:: 55 Before moving the index into its final destination 56 create an empty .keep file for the associated pack file. 57 This option is usually necessary with --stdin to prevent a 58 simultaneous 'git repack' process from deleting 59 the newly constructed pack and index before refs can be 60 updated to use objects contained in the pack. 61 62--keep='why':: 63 Like --keep create a .keep file before moving the index into 64 its final destination, but rather than creating an empty file 65 place 'why' followed by an LF into the .keep file. The 'why' 66 message can later be searched for within all .keep files to 67 locate any which have outlived their usefulness. 68 69--index-version=<version>[,<offset>]:: 70 This is intended to be used by the test suite only. It allows 71 to force the version for the generated pack index, and to force 72 64-bit index entries on objects located above the given offset. 73 74--strict:: 75 Die, if the pack contains broken objects or links. 76 77 78Note 79---- 80 81Once the index has been created, the list of object names is sorted 82and the SHA1 hash of that list is printed to stdout. If --stdin was 83also used then this is prefixed by either "pack\t", or "keep\t" if a 84new .keep file was successfully created. This is useful to remove a 85.keep file used as a lock to prevent the race with 'git repack' 86mentioned above. 87 88 89Author 90------ 91Written by Sergey Vlasov <vsu@altlinux.ru> 92 93Documentation 94------------- 95Documentation by Sergey Vlasov 96 97GIT 98--- 99Part of the linkgit:git[1] suite
