  • git clean -i

Manage Branch

• List local branches
  • git branch --list
• List remote tracking branches
  • git branch -r
• List both remote and local branches
  • git branch -a
• Delete branch
  • git branch -d <branch_name>
  • git branch -D <branch_name> (Force delete. Use with caution)
• Merge branch
  • git merge <branch-name>
• Rebase current branch with other branched interactively
  • git rebase -i <other-branch>
• Merge using merge commit
