Implemented Commands and Their Functionalities

1. Initialization (init command): Sets up a new, empty repository at a specified or default directory location, laying the groundwork for version control and subsequent development activities.

2. File Information (cat-file command): Retrieves detailed commit information like an associated tree, parent commit, author, committer, timestamp, and commit message without altering the repository.

3. Object Hashing (hash-object command): Generates unique identifiers for objects or files, aiding effective change tracking and data integrity verification.

4. Commit History (log command): Creates a visual commit history representation using Graphviz, encapsulating project evolution, branches, commits, and merges in a PDF format.

5. Listing Files (ls-tree command): Provides a structured view of files and directories within the repository, aiding in efficient file management.

6. List References (show-ref command): Displays repository references (branches, tags, etc.) alongside their respective commit hashes, aiding in understanding and tracking the repository's structure.

Running Commands

Initialization (init command) : To initialize a new repository

$ ./ualg init <directory>

File Information (cat-file command) : To retrieve detailed commit information

$ ./ualg cat-file -commit <commit-hash>

Object Hashing (hash-object command) : To generate unique identifiers for files

$ ./ualg hash-object <file>

Listing Files (ls-tree command) : To view files and directories in the repository

$ ./ualg ls-tree -r <branch>

List References (show-ref command) : To display repository references and their commit hashes

$ ./ualg show-ref

Commit History (log command) : To generate a visual commit history representation

• Generate the log file: $ ./ualg log > log.dot
• Convert the log file to PDF using Graphviz: $ dot -O -Tpdf log.dot
