git-index-pack - Linux
Overview
git-index-pack creates a new packfile that contains the objects necessary for creating the commit objects listed in a git index file. The main purpose of packfiles is to reduce disk and network usage during version control operations, such as pushes and pulls.
Syntax
git index-pack [options] <output_pack> <input_index>
Options/Flags
- -p | –progress: Show progress while creating a packfile.
- -v | –verbose: Enable verbose output to provide detailed information about the process.
- -n | –dry-run: Perform a dry run without actually creating the packfile. Just show what would have been done.
- -m | –memory-limit=
: Set the maximum memory size in bytes that can be used during object processing. Defaults to 256 MB. - -c | –check: Verify the integrity of the existing packfile against the index file.
- -r | –recompress: Recreate pack with new pack version, recompressing all objects.
- -i | –include-tag: Include tag objects in the pack.
- -t | –threads=
: Set the number of threads to use for pack creation. Defaults to the number of CPU cores. - -u | –unpacked: Create an unpacked file to use with
git-unpack-objects
.
Examples
Create a Packfile from a Git Index
git index-pack example.pack example.idx
Create a Packfile with Progress and Verbosity
git index-pack -pv example.pack example.idx
Check the Packfile Integrity
git index-pack -c example.pack example.idx
Common Issues
- Error: Index file corrupted: The git index file might be damaged or corrupted. Run
git fsck
to check and repair any issues. - Error: Out of memory: Increase the
--memory-limit
option to allocate more memory for object processing. - Error: Invalid input parameters: Check the spelling and syntax of the provided packfile and index file paths.
Integration
- git-pack-objects: Create a packfile directly from raw objects.
- git-unpack-objects: Initialize a git repository by extracting objects from a packfile.
- git-fsck: Check and repair a git repository, including packfiles.
