7 git commands that every developer should know.

Brian Munoz

Everyone should know how to use a version control because it is important to be able to see your history of code you been working on.

Git is a very powerful and a common version control system.

what is git

It is a popular version control system

tracks changes between files, and creates commits which are checkpoints that you can revert to
synchronize code between multiple people
create alternate branches to store different versions of code

relevant commands

There is a lot of commands. Here are a few important commands that everyone should know.

git init

creates a git repository in your current directory
creates .git/ folder in your working directory

This is where everything is stored.

git clone [url]

Copies a git repository located at url into a new directory in your working directory. Includes all files, history and branches.

A “fork” on Github will create your own copy of a repository. (makes you the owner of a new copy)

git status

Shows current state of the repository. Displays changed files, added files, and removed files.

In simple terms it shows you the status of everything.

git add [path]

Tell Git to include all the files at a [path] in the next commit. If you modify the files after git-adding them, git will remember their initial state when you added them.

To cancel the git add use the git reset. which just undos git add.

git reset [path]

undoes a git add
remove files from the index

what is index

Index is tracking the difference between the working directory and any commits you make. Index are things that are staged for next commit.

git reset [–soft | –hard] [commit]

restores state to a specific commit

– soft flag will not affect files – hard files will discard all changes

git commit [-a] [-m [message]]

creates a new checkpoint in the project status along with a message. Stores the state of any added files.

Use the -a flag to automatically add all tracked files (files already know to git from previous git add commands)

Use -m flag to use the message as the commit message

conclusion

Git is a very powerful tool to help you keep your files safe.

The commands every should know are…

git init
git clone [url]
git status
git add [path]
git reset [path]
git reset [soft hard ] [commit]
git commit [-a] [-m [message]]

why JavaScript methods are useful

You can think of a method as an action that a number, string or object can perform or have taken on it.

primitives vs objects

Primitives are immutable and passed by value. Objects are mutable and stored by reference.
