Git Sophisticated Commands

1. Compare two branches: branch_1 and branch_2:

   git diff branch_1…branch_2

2. Merge specified files of one branch(e.g. branch_name) into current branch:

   git checkout branch_name ./src/…/file1 ./src/…/file2 ./src/…/file3

3. Change the committed comments:

   git commit --amend
   

4. Reset and delete the remote URL:

   git remote set-url origin git://new.url.here
   git remote remove origin

5. Clone a single branch:

   git clone -b <branch> <remote_repo>
   git clone -b my-branch git@github.com:user/myproject.git

6. Ignore history after one commit and preserve changes locally:

   git reset <commit>
