A pull request (PR) is a mechanism in GitHub/GitLab/Bitbucket for proposing changes from one branch to another. It enables code review, discussion, and automated testing before changes are merged into the main branch.

The .gitignore file specifies patterns of files and directories that Git should ignore and not track. Common examples include compiled binaries, log files, and environment config files.

git status displays the state of the working directory and staging area. It shows which changes have been staged, which have not, and which files are untracked.

git fetch downloads changes from a remote repository but does not automatically merge them into the current branch. git pull fetches and merges in one step.

The command git branch <name> creates a new branch in Git. To also switch to it immediately, git checkout -b <name> or git switch -c <name> can be used.
