Test your grep command skills by completing the following tasks:

1. Create a file named diff.txt inside your ~/workspace/project-log/directory with the following format:

Version: 2.0 username: current_user < ~/workspace directory visible content list > 

2. Grep the differences between the~/workspace/project-log/changelog.txt file content against the ~/workspace/project-log/diff.txt file content and append the results to the ~/workspace/project-log/changelog.txt file

TIP: Try using autocompletion shortcuts, relative paths and string interpolation

Once you have completed these tasks press the Check It button to have your solution assessed.
