Summary - .gitignore

Combine patterns to write a project .gitignore file.

Create a project .gitignore

When creating a .gitignore file for a project, you can ignore temporary files, specific extensions, and generated directories using separate rules. Wildcards match multiple files, while directory patterns exclude specific directories. You can keep computer-specific personal rules in a global ignore file.

# .gitignore
*.log
*.tmp
build/
cache/

Separating project rules from personal rules helps keep repository files organized.

Exercise Write a project .gitignore file

Write these three rules on separate lines in .gitignore: ignore all .log files, all .tmp files, and the build/ directory. Do not add any other rules.
