  • #Push and reset

    $ git push origin -u <new_name>

  • #Delete remote branch

    $ git push origin --delete <old>

#Log

Search change by content

$ git log -S'<a term in the source>'

Show changes over time for specific file

$ git log -p <file_name>

Print out a cool visualization of your log

$ git log --pretty=oneline --graph --decorate --all

#Branch

List all branches and their upstreams

$ git branch -vv

Quickly switch to the previous branch

$ git checkout -

Get only remote branches

$ git branch -r

Checkout a single file from another branch

$ git checkout <branch> -- <file>

#Rewriting history
