Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
Its goals include speed, data integrity, and support for distributed, non-linear workflows (thousands of parallel branches running on different systems).
Git was created by Linus Torvalds in 2005 for development of the Linux kernel, with other kernel developers contributing to its initial development. Since 2005, Junio Hamano has been the core maintainer. As with most other distributed version-control systems, and unlike most client–server systems, every directory on every computer is a full-fledged repository with complete history and full version-tracking abilities, independent of network access or a central server. Software is distributed under GNU General Public License Version 2.
Create with Git
# Clone an existing repository git clone ssh://firstname.lastname@example.org/repo.git # Clone a unique branch from an existing repository git clone -b <branchname> --single-branch ssh://email@example.com/repo.git # Clone an existing repository and all its sub-modules recursively git clone --recurse-submodules ssh://firstname.lastname@example.org/repo.git # Create a new local repository git init
# Set the name attached to all your commits git config [--global] user.name <name> # Set the email attached to all your commits git config [--global] user.email <email> # Set colorization of command line output for all repos git config --global color.ui auto # Print set name (in current repository or globally) git config [--global] user.name # Print set email (in current repository or globally) git config [--global] user.email
# List changed files in your working directory git status # List changes to tracked files git diff # Add all current changes in file to the next commit git add <file> # Add all current changes to the next commit git add . # Add changes to the next commit interactively git add -p <file> # Rename file and add it to next commit git mv <file> <new file name> # Delete file and add its deletion to next commit git rm <file> # Commit all local changes in tracked files git commit -a # Commit previously staged changes git commit # Change the last commit git commit --amend # Note: You shouldn't amend published commits!
# Show all commits git log # Show changes over time for a specific file git log -p <file> # Show changes over time for a specific committer git log --author=<committer name> # Note: <committer name> is a pattern, so Ed will match Edward Smith. Quotes are optional if the pattern doesn't contain spaces. # Search (grep) commit messages for the given string git log --grep=<string> # Who changed what and when in file git blame <file> # Store changes temporarily git stash # Remove and apply stashed changes git stash pop # Remove file from all previous commits but keep it locally git rm --cached <file>
Branches & Tags
# List all existing branches git branch # Switch HEAD branch git checkout <branch> # Create a new branch based on your current HEAD git branch <new-branch> # Create a new tracking branch based on a remote branch git branch --track <new-branch> <remote-branch> # Delete a local branch git branch -d <branch> # Delete a remote branch git push origin --delete <branch> # Rename a branch locally git branch -m <old name> <new name> # Rename a branch on remote git push <remote> :<old name> git push <remote> <new name> # Tag the current commit git tag <tag-name>
Update & Publish
# List all currently configured remotes git remote -v # Show information about a remote git remote show <remote> # Add new remote repository git remote add <remote> <url> # Rename a remote git remote rename <old-name> <new-name> # Download all changes from remote, but don't merge into HEAD git fetch <remote> # Download all changes from remote, but don't merge into HEAD and clean up deleted branches from origin git fetch -p <remote> # Download changes and directly merge into HEAD git pull <remote> <branch> # Publish local changes on a remote git push <remote> <branch> # Track a remote repository git remote add --track <remote-branch> <remote> <url> # Publish your tags git push --tags
Merge & Rebase
# Merge branch into your current HEAD git merge <branch> # Rebase your current HEAD onto branch git rebase <branch> # Note: You shouldn't rebase published commits! # Abort a rebase git rebase --abort # Continue a rebase after resolving conflicts git rebase --continue # Resolve conflicts using your configured merge tool git mergetool # Manually resolve conflicts using your editor and mark file as resolved git add <resolved-file> git rm <resolved-file>
# Discard all local changes in your working directory git reset --hard HEAD # Discard local changes in a specific file git checkout HEAD <file> # Revert a commit by providing a new commit with contrary changes git revert <commit> # Restore a specific file from a previous commit git checkout <commit> <file> # Reset your HEAD pointer to a previous commit ## Discarding local changes: git reset --hard <commit> ## Preserving all changes as unstaged changes: git reset <commit> ## Preserving uncommitted local changes: git reset --keep <commit>
Maybe conda commands also will be useful.
