Identify available and currently selected branch

• Use the git branch command

Jons-MacBook:vscaler-openhpc Jon$ git branch
* jon-test
  master

Switch to different branch

• Switch to the top level directory for the local copy of your repo
• Use the following commands:
  • git fetch to download objects and refs from another repository.
  • git checkout <branch_name> to switch to another branch (and specify the branch name)

Jons-MacBook:vScaler-scripts Jon$ cd vscaler-openhpc/
Jons-MacBook:vscaler-openhpc Jon$ git fetch && git checkout jon-test
Branch jon-test set up to track remote branch jon-test from origin.
Switched to a new branch 'jon-test'

Identify changes

• Use the git status command

Jons-MacBook:python Jon$ git status
On branch jon-test
Your branch is up-to-date with 'origin/jon-test'.
Untracked files:
  (use "git add <file>..." to include in what will be committed)

	hello.txt

Add a modified file to your local index

• Use the git add <filename> command

Jons-MacBook:python Jon$ git add hello.txt

• And confirm with git status

Jons-MacBook:python Jon$ git status
On branch jon-test

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)
