Git allows users to set up SSH keys to clone repositories securely. The document outlines how to generate a public key, add it to your account, and clone a repository using SSH. It then provides commands for branching, committing, pushing, pulling, adding, cleaning, resetting, merging, stashing, deleting branches, and viewing logs in Git. Finally, it asks several interview questions about Git concepts like repositories, commits, staging areas, branching, cloning, configuration, advantages, and functions of common Git commands.

1. SET UP SSH FOR GIT ON LINUX
1
Generate your Public key using ssh-
keygen command and set your
passphrase.
2
Copy the public key from your
system and paste it to your
bitbucket account under ssh key
section.
3
Add the key and now try to clone a
repository using the mentioned
passphrase.

2. CLONING REPOSITORY AND PUSH
OPERATION
git branch list all the branch
git clone [ repository URL ] Clone an existing repository
git add . Puts current working files into the stage
git commit –m “comment” Commits staged changes to a local branch
git push origin master Uploads changes from all local branches to the
respective remote repositories.

3. GIT OPERATIONS
git checkout [branch name] - Switch to specified branch
git pull origin [branch name] - fetch the latest changes to the working directory
git checkout –b [branch name] - create a new branch and switched to that
git status - shows the status of operation
git add [./folder/file] - It will add the files to staging
git push origin [branch name] - It will push the changes to the remote repository
git clean –f - delete all changes along with untracked files.
git reset HEAD [file] - to unstage or undoing

4. git merge -It will merge the changes from other branch to current branch
git log -It will show the logs with commit code
git revert [commit code] - It will undo the changes
git stash - It saves your local modifications away and reverts the working
directory to match the HEAD commit.
git branch –D branch_name - for deleting a branch

5. WEBHOOKS
Webhooks allow you to
build or set up
integrations, such as
GitHub Apps or OAuth
Apps, which subscribe to
certain events on
GitHub.com.
Webhooks can be used to
update an external issue
tracker, trigger CI builds,
update a backup mirror, or
even deploy to your
production server.
