Day 08/90 Task: Basic Git & GitHub for DevOps Engineers
Git is a distributed version control system (DVCS) that multiple developers and other contributors can use to work on a project. It provides a way to work with one or more local branches and then push them to a remote repository.
?
GitHub is a cloud platform that uses Git as its core technology. GitHub streamlines project collaboration by offering a website, command-line tools, and a cohesive workflow for developers and users to work together. GitHub act s as the remote repository mentioned earlier.
?
git add
git add is the command you use to tell Git to start keeping track of changes in certain files.
The technical term is staging these changes.
?
git commit
After you've staged some changes for commit, you can save your work to a snapshot by invoking the git commit command.
?
git log
The git log command allows you to see information about previous commits. Each commit has a message attached to it (a commit message saved.
?
git help
You've already tried out the git help command, but it's worth reminding you about. Use this command to easily get information about all the commands you've learned so far, and more.
?
Exercises:
?
Create a new repository on GitHub and clone it to your local machine.
?
Repo : Day8-sample-task
ubuntu@DevOps:~$ git clone https://github.com/ds-kamran/day8-sample-task.git
Cloning into 'day8-sample-task'...
warning: You appear to have cloned an empty repository.
?
Make some changes to a file in the repository and commit them to the repository using Git.
?
ubuntu@DevOps:~$ cd day8-sample-task/
ubuntu@DevOps:~/day8-sample-task$ vi index.txt
ubuntu@DevOps:~/day8-sample-task$ ls
index.txt
ubuntu@DevOps:~/day8-sample-task$ git add .
ubuntu@DevOps:~/day8-sample-task$ git commit -m "An empty index.txt file has been created" index.txt
