Getting Started With Git Commands

As a software engineer, we need to collaborate on multiple projects with the engineering team. For that, Git is one of the most used and recommended Version controlling system that the industry is using on a daily basis. Therefore, at the early stage of my engineering career, I also needed to know the basic commands of git in order to have a better synchronization with the team and the projects we will be working on.

Today I will be sharing my knowledge on git and its commands to get started with your initial projects.

There are 4 stages:

Workspace : This is the folder/Location/Directory where we start our project.
Staging : Making candidates to be committed to the local repository.
Local Repository : After staging, we need to commit changes to here.
Remote Repository : After committing, we can push our changes to the Remote Repository.

Now, Lets Explore the commands to work on all the above mentioned steps.

To initialize a new local repository in your workspace :
```
 git init
```

To configure user globally

 git config --global user.name "name"
 git config --global user.email "mail"

To configure user specifically for specific project

 git config user.name "name"
 git config user.email "mail"

To see the config
```
 git config --list
```

For Staging

 git add --all
 git add .
 git add filename

For commit
```
 git commit -m "msg"
```
To see all commit details shortly
```
 git log --oneline
```
Going back to previous Stage
```
 git checkout 'CommitCode'
```
See changes of a commit
```
 git show ‘CommitCode’
```
See difference between 2 commits
```
git diff commit1code commit2code
```
To remove a file from git
```
git rm file.txt
```
Delete a file from Workspace
```
git rm filename
```
Remove a file from Staging (Untrack)
```
git reset HEAD filename
```
Create New Branch
```
git branch branchName
```
See All Branches
```
git branch
```
Switch branches
```
git checkout branchname
```
Create branch and switch to that branch
```
git branch -b branchName
```
Let Local Repo know that there is a change in Remote repo
```
git fetch
```
Get the changes of Remote in Workspace
```
git pull
```
Merge 2 branch (From present branch)
```
git merge OtherBranchName
```
Save the file to temporary folder, So we don't loose that
```
git stash
```
Get the file from stash
```
git stash pop/apply
```
List of stash
```
git stash list
```
Go to specific Stash
```
git stash pop stashCode
```
Remove untracked Files
```
git clean -f
```

To Ignore a file

Create a .gitignore file
touch .gitignore // will create the ignore file.

Use HTTP Link to connect with remote repository.
```
git remote add origin httpLink
```
