Frequently used git command

Details

There are some cases I need to use some specific git commands for some special purposes, like 

• Undoing git merge which haven't be pushed
• git reflog (Get the commit desired to return)
• git reset --hard sha
  
  
• Cherry-picking specific file changes from 1 commit to another
• git checkout <branch or sha of commit> -- filename
  
  
• Retrieve just 1 file from specific branch
• git checkout experiment -- app.js
  
  
• Show content changes which have been staged
• git diff --cached
  
  
• Show the diff of the same file between different commits of the same branch
• git diff HEAD^^ HEAD someFile (Show differences of someFile 2 commits before HEAD)
  
  
• Show file changes on specific commit (without diff information)
• git show --pretty="" --name-only {commit-sha}
  
  
• Show commits differences between 2 branches since branch created (file list)
• git log --oneline master..myBranch (Show changes since master branch)
• git log --oneline --no-merges master..myBranch (Show changes since master branch skipping merge commits)
  
  
• Get a list of branches created ordered with create date
• git branch --sort=-committerdate  # DESC
• git branch --sort=committerdate  # ASC
  
  
• Commit with standard input
• echo -e 'Update version number to v1.6.72.0\n\nfrom v1.6.70.0 to v1.6.72.0' | git commit /home/jacky/Documents/gitproj/p2_controller/docker/docker-compose-prod.yml /home/jacky/Documents/gitproj/p2_controller/docker/docker-compose-prod-upgrade.yml /home/jacky/Documents/gitproj/p2_controller/p2_controller/static_data/VERSION -F -
