Working with Git
Git is a version control system designed to handle small projects to large projects in a effective way. This post explains on how to use git commands and how to handle git repositories,etc.,
Git repositories are the location where you can store the all your project/application code. It could be either on github account or your own private repositories such as gitlab or bitbucket account,etc.,
Normally, there are two ways to clone the repositories. One is via http protocol or other way is to use SSH protocol.
The below command is to clone the git repository to your local machine using https protocol.
git clone https://gitrepourl/repo.git
This will create a directory called repo on your local machine.
Incase, if we receive an error git command not found, we need to install git on the machine.
apt-get install git
yum install git
Now, we can setup git on the machine.
git config --global user.name "Your Name"
git config --global user.email "email@example.com"
So far, we have cloned the repository and setup git. Now, we are making changes the files and commit to the repository.
We are creating a file test.html on your local machine and push it to git repository.
Now, add the file to git repository
git add test.html
Commit the file with your changes.
git commit -m "Adding test.html"
Add remote repository to origin.
git remote add origin https://gitrepourl/repo.git
Push the changes to the remote origin.
git push origin master
Origin is remote URL
master is a local repository.
The above example is a simple one which explains on how to push a single file to git repo. In this section, we will explain few more git command which can help on how to use git effectively.
To show recent changes, current commits,etc.,
To view the remote repository.
git remote -v
To view the git log and commit IDs.
To stash all the local changes
To create a new branch from master
git branch name-of-branch
To checkout to another git branch.
git checkout -b name-of-branch
To merge a branch to master. First Checkout to master branch and merge the branch
git checkout master
git merge name-of-branch
To delete a file from git branch. First delete the file, commit and push the file.
git rm test.html
git commit -m "Delete from git"
git push origin master
To move to previously saved git commit.
git reset --hard HEAD~1
