Compiler Error

This week's Compiler Error has a theme: Git commands!
1 - git whatchanged --since="2 weeks ago" will show a log of commit messages that have been made since 2 weeks ago.
2 - git add -p will allow you to stage hunks of code interactively from the command line.
3 - git worktree add allows you to checkout a specific branch to a separate directory.
4 - git grog generates an ascii-art graphical log showing branch points leading up to the current commit.
