Navigating Git

The Git Graph

Everything we do in a git repository can be represented by a Graph

This graph can also have branches. By default we have one branch called master . Our current position (Where we are coding) in the git graph is pointed by a pointer called Head.

Going to a specific commit

To checkout a previous commit, you will use the Git checkout command followed by the commit hash you retrieved from your Git log

git checkout <commit hash>

Deleting until a Previous Commit

Let’s say in the above graph we want to delete Commit 3 and Commit 2. We can use

git reset <the hash of commit 1 will come here>

All the files of the deleted commits will become unstaged files.

To completely delete those files rather than staging them we can do

git reset --hard <hash> 

Please note: The hash we enter is the hash of the commit where your head should be after deletion.
