Study Notes
Version Control
- Version control, also known as source control or revision control, is the practice of managing changes to a set of files over time.
- It is commonly used in software development to track changes made to the source code of a software project.
Centralized VCS
- Centralized VCS, such as Subversion, CVS, and Perforce, track version data on each individual file.
Git
- Git keeps "snapshots" of the entire state of the project, with each check-in having a copy of each file.
- This method has more redundancy but is faster.
Git Local Areas
- In a local Git repository, files can be:
- Committed (in the local repository)
- Modified but not yet committed (in the working copy)
- In the "staging" area (ready to be committed)
Basic Git Workflow
- Modify files in the working directory
- Stage files, adding snapshots of them to the staging area
- Commit, which takes the files in the staging area and stores that snapshot permanently to the Git directory
Git Commands
-
git clone url localDirectoryName: clones a remote repository to the current directory -
git add filename: adds file contents to the staging area -
git commit -m "commit message": records a snapshot of the staging area -
git status: views the status of files in the working directory and staging area -
git diff: shows the diff of what is staged and what is modified but unstaged -
git help [command]: gets help info about a particular command -
git pull: fetches from a remote repository and tries to merge into the current branch -
git push: pushes new branches and data to a remote repository
Adding and Committing a File
-
git add filename: adds file contents to the staging area -
git commit -m "commit message": takes a snapshot of these files and adds them to the repository
Viewing Changes
-
git statusorgit status -s: views the status of files in the working directory and staging area -
git diff: shows what is modified but unstaged -
git diff --cached: shows a list of staged changes -
git logorgit log --oneline: shows a log of all changes in the local repository
