[Git] Review git fetch, merge, pull, and push

Basic Git Review

• git fetch
  
  • to see if there needs any update
  • downloads content from the specified remote repository
• git merge
  • merge the remote content refs and heads into a new local merge commit. 

 

EXAMPLE:

• git pull
  • download all the changes from the point where the local and main diverged
  • We makes this often to keep our directory up to date and finally merge it with our main branch.
  • We often make pull requests early.
  • When we do commit or push, we can send codes using pipelines to test our codes. 

H point
