How difficult was Git in its first week? Linus Torvalds explains

Key Concepts:

• Git Kernel Development
• Plumbing Commands (raw Git commands)
• Commit Tree
• SHA (Secure Hash Algorithm)
• Head File
• Porcelain (user-friendly Git interface)
• Shell Scripts
• Source Control

Early Git Usage and Development

The speaker describes their initial experience using Git for kernel development as extremely rudimentary. In the first week, they were directly using the raw "plumbing commands" (low-level Git commands) manually. There was no higher-level interface or abstraction to make Git user-friendly.

Manual Commit Process

The speaker details the arcane process of making a commit. It involved using commands like "commit-tree," which would return a SHA (a unique identifier for the commit). The user would then have to manually write this SHA into the "head file" to finalize the commit. This process was entirely manual and lacked any user-friendly tools.

Early Porcelain and Shell Scripting

To improve usability, the speaker created shell scripts around these difficult-to-use plumbing commands. These scripts represented the early "porcelain" (user-facing interface) of Git. However, even with these scripts, Git remained challenging to use.

Unexpected Early Adoption

The speaker expresses surprise at the rapid adoption of Git by source control professionals. Within days of the initial Git release, they started receiving patches and contributions from external developers. This indicates a strong early interest in Git despite its initial complexity.

Notable Quotes:

• "the first week when I was using it for the kernel I was literally using the raw what is now called plumbing commands by hand"
• "to to make a commit you'd do these very arcane things like commit tree yeah commit tree and that just returns a like shaw that you by hand just write into the head file and that was it"
• "I was actually surprised by how quickly some source control people started coming in and I started getting patches from the outside within days of the first get version"

Logical Connections:

The speaker establishes a clear progression from the initial raw, manual Git usage to the development of shell scripts to improve usability. This progression highlights the evolution of Git from a purely technical tool to a more accessible source control system. The unexpected early adoption underscores the potential and appeal of Git even in its nascent state.

Synthesis/Conclusion:

The initial experience of using Git for kernel development was characterized by manual execution of low-level commands. The creation of shell scripts marked the beginning of a user-friendly interface. The rapid adoption and contribution from external developers demonstrated the early potential and appeal of Git, despite its initial complexity.
