Git Contd

• What Git Commit is?
  
• Work done so far
  
• We have create a new folder and done the activites as shown below
  
  
• Now lets check for status
  
• Lets make 3 changes (2 in existing files in commit and create a new file)
  
• In Git Untracked files are the files that were not part of local repo and a new file is created.
  
• Now commit the changes
• 
• HEAD is a pointer which generally points to latest commit, Working tree will populate the contents based on HEAD which refers to commit
• Add some changes to staging area
  
• To remove the changes from working tree for a tracked file
  
• Lets see how to remove untracked which is in staging area
  
  
  
• Now lets create a 3 commit
  
• git log in short form git log --oneline
  
• In Git by default there will be one branch which is called as master which looks at latest commit id.
• Checkout commands moves the HEAD position. By default as master points to latest commit, HEAD points to master. IF you want navigate back in history git checkout <commit-id> to get back to latest commit git checkout master
• Note: checkout has other flavors which we are yet to know.
