• Commands related to a remote repository:

  • git clone git@github.com:USER-NAME/REPOSITORY-NAME.git

  • git push or git push origin main (Both accomplish the same goal in this context)

• Commands related to the workflow:

  • git add .

  • git commit -m "A message describing what you have done to make this snapshot different"

• Commands related to checking status or log history

  • git status

  • git log

The basic Git syntax is program | action | destination.

For example,

• git add . is read as git | add | ., where the period represents everything in the current directory;

• git commit -m "message" is read as git | commit -m | "message"; and

• git status is read as git | status | (no destination).

Delete commits:

git reset --hard HEAD~1 - delete last commit                                                       

You can also remove up to a specific commit using a commit’s hash, like so:

git reset --hard <hash>

To delete commits from remote, you will need to push your local changes to the remote using the git push command.

git push origin HEAD --force

git reset --soft HEAD~1
