gitsum

A CLI application that generates checksum of files contained in a store directory and tracks the corresponding checksums files in repo directory using git, mirroring the directory structure of the store directory.

Example

Store:

├── dir-a
│   └── file-a:             actual `file-a`
│── dir-b
└── file-c:                 actual `file-c`

Repo:

├── dir-a
│   │── file-a.md5:         md5 checksum of `file-a`
│   │── file-a.sha256:      sha256 checksum of `file-a`
│   └── file-a.sha512:      sha512 checksum of `file-a`
│── dir-b
│── file-c.md5:             md5 checksum of `file-c`
│── file-c.sha256:          sha256 checksum of `file-c`
└── file-c.sha512:          sha512 checksum of `file-c`

Usage

Create Checksum Files

Create checksum of store in git repository:

gitsum -repo <repo-dir> -store <store-dir>

where

• <repo-dir>: path to the git repository to store the checksum files
• <store-dir>: path to the directory of the store, containing all the files to create checksum files for

Export Checksums

Export checksums from repository to (md5|sha256|sha512sum) compatible checksums files:

gitsum-export -repo <repo-dir> -hashfile <hash-file> -algorithm <algorithm>

where

• <repo-dir>: path to the git repository where the checksum files are stored
• <hash-file>: path to checksums file to generate, e.g. MD5SUMS, SHA256SUMS, SHA512SUMS
• <algorithm>: hash algorithm to generate export file for. Currently on md5, sha256, sha512 are supported
