Copy an existing remote repository

1. Clone a remote repository.
   • Select a local folder to copy the repository into, or create a new folder if you prefer. The repository will be copied as a subdirectory of the selected folder.
   • At a command or terminal prompt, navigate to the selected folder.
   • Clone the repository using the command:
     git clone URL_TO_REPO. See also: git pull and git fetch

Create a local repository

1. Initialize a folder for Git.
   • Select a local folder to add to Git, or create a new folder if you are starting a new project.
   • At a command or terminal prompt, navigate to the selected folder.
   • Initialize the folder using the command:
     git init

Repository information

• git remote -v or git remote show origin or git config --get remote.origin.url

git log

git log, git shortlog, git log --all, git log --oneline

git show

• git show 3c88ad72430

Tags / Releases

• Show all tags in git log: git log --no-walk --tags --pretty="%h %d %s" --decorate=full
• git tag (show releases)
• List tags with dates: git log --tags --simplify-by-decoration --pretty="format:%ci %d". Just can also add taglog = log --tags --simplify-by-decoration --pretty='format:%ci %d' (note the single-, NOT double-quotes) in the [alias] section of your gitconfig file.

Miscelaneous

• git log --decorate=full --simplify-by-decoration
• Print lines matching a pattern:git grep TEXT_TO_SEARCH
• git merge
• Move existing, uncommitted work to a new branch in git

Tips and Tricks

• To avoid using --pager in all git log commands, add the following line to your ~/.bash_profile file:
  export GIT_PAGER=cat
