Git is a popular version control system made by Linus Torvalds.
Download Git for Windows
sudo apt install git git-lfs
# Clone or download a repository git clone <url> [<foldername>] # cd into the cloned folder cd <foldername> # Note that some repos have submodules which will also need to be cloned git submodule update --init --recursive # Stage your changes git add <my files> # Or stage all files # git add . # Make a commit git commit -m "My commit message" # Push your changes to the repository git push # Pull the latest changes from the repository # Equivalent to git fetch && git merge FETCH_HEAD git pull
You should make branches per-feature.
This allows you to work on your feature from a static copy of the code repo.
You can also discard this branch if you decide the feature is no longer needed.
Once the feature has been fully developed, you should rebase the branch onto the head of master.
Then you can merge the branch to add the feature to master.
# Make a branch git checkout -b my_feature # Add and commit to this branch git add . git commit -m "My commit message" # Push git push --set-upstream origin my_feature # Checkout a branch git checkout my_branch # Checkout a single file from another branch git checkout my_branch -- other_file.txt
Pull requests are a way to submit changes to repositories you do not manage.
First, you fork the repository to create a working-copy for yourself to develop on.
Once your changes are finished, you create a pull request asking the original repo to incorporate your changes.
It's easiest to just use the web interfaces of GitHub or GitLab for this.
To do this manually, see Git Book: Contributing to a project.
How to migrate repositories to another Git server
git clone --mirror <original_repo> cd <repo> # Run the following lines only if you're using lfs git lfs fetch --all git lfs push --all <new_repo> git push --all <new_repo>
Changing Remote URL
You will need to change the remote url if it is changed on the server. E.g. if you change the project name.
git remote set-url origin <new-url>
.gitignore is used to ignore certain files to make sure they do not get accidentally pushed to the remote git repo.
You can find a collection of .gitignore files on Github's gitignore repo.
Or you can create a custom .gitignore file at gitignore.io.
.gitattributes are used to give attributes to paths.
They can be used to assign programming languages to filenames.
They are also used to identify which files should be stored in the lfs.
Here is an example to store video and images in the lfs.
## Video *.mp4 filter=lfs diff=lfs merge=lfs -text *.mov filter=lfs diff=lfs merge=lfs -text *.flv filter=lfs diff=lfs merge=lfs -text ## Pictures *.png filter=lfs diff=lfs merge=lfs -text *.jpg filter=lfs diff=lfs merge=lfs -text *.jpeg filter=lfs diff=lfs merge=lfs -text ## Binary files *.bin filter=lfs diff=lfs merge=lfs -text *.7z filter=lfs diff=lfs merge=lfs -text
git clean to delete untracked files.
-x to also delete gitignore'd files.
# Force delete any untracked files and directories git clean -fd
