3. Start the ssh-agent in the background

Using .gitignore

1. Single file
   • Put the exact filename.

      .DS_Store
     

2. Directories
   • Include their paths and putting a / on the end.
   • If / is not present, it will match both files and directories with that name.

      node_modules/
      logs/
     

3. Negation
   • Use a prefix of ! to negate a file.

      !example.log
     

4. Double Asterisk
   • ** can be used to match any number of directories.
     
   • **/logs matches all files or directories named logs
     
   • **/logs/*.log matches all files ending with .log in a logs directory
     
   • logs/**/*.log matches all files ending with .log in the logs directory and any of its subdirectories.
     
   • logs/** matches all files inside of logs.
5. Comments
   • Any lines that start with # are comments.

      # macOS Files
      .DS_Store
