Silly, Verbose Git Lesson

This is a better formatted replica of my command log from my simple Git Tutorial on Github. Probably only useful to me. I know enough git to commit things but as a solo developer on my project, I haven’t had a need to go further.

Command Log

Here are all the commands I’ve used so far:

git init
This command created the repo
git add README.txt
Added the README.txt file to the staging area
git commit -m "Initial commit"
Did an initial commit with that README.txt file

hmm… I should probably define some terms. What is a staging area?

Time to BRANCH OUT and start a new feature! ahahahaha…

git checkout -b git_terminology
This command created a new branch where I’ll create a git_terminology.md file

I created a file with some basic terminology and added it.

git add git_terminology.md

Time to get it committed.

git commit -m "Added terminology file"

I should probably add a line about this change to the README so people will know what’s in that file.

Since README.txt is already tracked, I can use git commit -am and a message to add all changes to tracked files to the current commit.

git commit -am "Updating README.txt with git_terminology.md"

I made a mistake and need to undo the last commit!

git reset --soft HEAD~1

This will undo the commit but preserve the changes I made so I can patch it up. No one will be the wiser. EVIL LAUGH.

Time to commit this change again and switch back to the master branch for some more work there.

git commit -am "Updating README.txt with git_terminology.md"
Same command as last time, but I fixed my mistake!

git checkout master

Here I am safely back on the master branch.

I just realized, my command_log.md file isn’t staged! Time to remedy that.

git add command_log.md

While I’m here, I think I should add a KEY FILES section to the README to join that mention in the other branch.

Since both these files are already tracked, I’ll run git commit with the -am switches

git commit -am "Added key files section to the readme"

I think that other branch is all done being developed. Time to merge it back in.

git merge git_terminology

AN ERROR?! Say it ain’t so.

Auto-merging README.txt
CONFLICT (content): Merge conflict in README.txt
Automatic merge failed; fix conflicts and then commit the result.

How can I fix this…

Since I’m in Visual Studio Code, I went to the git plugin and see a ‘C’ beside the README.txt file… That might mean there’s a conflict to solve!

Identifying Conflict in VS Code

Clicking on the file actually shows the diff. I want to keep both changes though, so I’ll click that option.

Identifying Merge Conflict in VS Code

Now that I’ve fixed the conflict, I’ll create a commit with that un-broken file.

git commit -am "fixing merge conflicts"

What does the log say now?

git log --oneline

db50789 (HEAD -> master) fixing merge conflicts
1f37354 Added key files section to the readme
072783b Added command_log.md file
662f04c (git_terminology) Updating README.txt with git_terminology.md
24141f2 Added terminology file
73a2238 Initial commit

Perfect. Time to commit this last change to the command_log.md file and be done with it, for now.
