Git, GitHub and Git Commands (70+ git commands)

WHAT IS GIT?

A lot of times, people are confused on the right commands to use to resolve git issues and the steps to take in resolving those issues. Hence spending more time researching, trying, and working. This takes time, reduces code time and increases the complexity of work.

Git is a version control software that is free and open source used to track changes in any set of files and to manage projects from small to medium to large projects. It helps to coordinate work amongst programmers and is efficient, fast and supports distributed and non-linear workflows.

Git can be accessed on all PCs from Windows to mac to Linux. Git tracks files, contents, and coordinates projects.

DIFFERENCE BETWEEN GIT AND GITHUB

Git is a version control software that tracks and manages contents, files and projects while Github is a cloud-based hosting service used to manage git repositories. So, in essence, github manages git repos but git provides the tracking and coordinating service hosted on github. Git repositories are generally local repos and can be stored in the cloud using github. So basically, github is a tool for working with git. There are other services to host git. They include:
Bitbucket, GitLab, Perforce, Beanstalk, Amazon AWS CodeCommit, Codebase, Microsoft Azure Devops, SourceForge.

Another difference is in the ownership: Github is owned by Microsoft Corporation while git was built by Lins Torvalds, the creator of Linux.

GIT COMMANDS

There is a long list of git commands available to git users regardless of the git hosting service being used.

1. git config -1: This command returns a list of information about your configuration. It includes name and email.

4. git config –global credential .helper cache: It helps you store login credentials in the cache so you don’t have to type them in every time.

5. git init: This is usually the first command you use when working with repos. It is used to initialize a new git repo locally in your project root.

1. git status: This command shows the status of the current repo including staged, unstaged and untracked files.

10. git commit: This command will open a text editor in the terminal so you can write a full commit message. A commit message is a short summary of changes, an empty line and a full description of the changes after it.

11. git commit -m “write your commit message here”: This command helps you specify a short summary for your commit without the text editor and also, it commits all added files.

13. git log: This command shows the commit history for the current repository.

14. git log -p: This command history including all files and their changes.

25. git revert: This command is used to rollback the last commit in git. It will create a new commit that is the opposite of everything in the given commit. ‘Git revert HEAD’

26. git revert commit_id_here: This command is used to revert an old commit using its commit id. It opens the editor so you can add a commit message.

27. git branch branchname: This command helps you create a new branch. By default, you have one branch, the main branch. You can however create a new branch. Git won’t switch to it automatically. We would need to switch to it.

28. git checkout branch_name: This command helps you to switch to another branch. After creating a new branch, you can switch over.

29. git branch: This helps list out the available branches for that project and it marks the current branch with an asterisk and highlights it in green.

30. git checkout -b branch_name: This is used to create a new branch as well as switch over to the new branch immediately.

32. git merge branchName: This command is used to merge the history of the branch you are currently in with the branchName branch.

33. git log –graph –oneline: This command is used to show the commit log as a graph in git. –oneline will limit commit messages to a single line.

40. git branch -r: This command is used to show the name of all remote branches that git is tracking for the current repository.

41. git fetch: This command will download the changes from a remote repo but will not perform a merge on your local branch(as git pull does that instead). It fetches remote repo changes.

42. git log origin/main: This command is used to check the current commits log of a remote repo in git.

43. git merge origin/main: This command is used to merge a remote repo with your local repo in git.

44. git remote update: This command is used to get the contents of remote branches in git without automatically merging. It lets you update the remote without merging any content into the local branches.

45. git push -u origin branchName: This command is used to push a new branch to a remote repo in git. -u creates the branch upstream.
