I wished I could undo mistakes that I made in my life by using git :’)

This video saved me! About 2 weeks ago I deleted a commit and tried everything to could think to get it back. Discovering git reflog, then resetting or creating a new branch from that commit is exactly what I needed. And voilà, all work restored after many sleepless nights. THANK YOU SO MUCH!

Another good tip is when we have worked on a file but want to commit only parts of it, we can use the -p option to decide which lines should and shouldn't be staged.

Great video. I like how you presented the use cases.

[privatename]

Fantastic video. And very comprehensive. Only thing is that you never gave the CLI commands for the last exercise, "Splitting / Editing and Old Commit." I took good notes on everything else. Thanks for this post.
