• git checkout [branch-name]: Switch to the specified branch
• git checkout -b [branch-name]: Create and switch to a new branch
• git merge [branch-name]: Merge the specified branch into the current branch

💡 Cheat Sheet Tips 📌

• Combine Commands: Use && to chain commands (e.g., mkdir new-dir && cd new-dir).
• Use Wildcards: * matches multiple files (e.g., rm *.txt deletes all .txt files).
• Shortcut Branch Switching: git checkout - switches back to the previous branch.
• Use Aliases: Set up aliases for frequently used commands (e.g., alias gs='git status').
