AI Summary: The `whoami` command, when given an invalid argument like `--typo`, incorrectly suggests `whoami-usage` in its error message instead of `whoami`. The issue proposes correcting this so that the usage message consistently refers to the `whoami` command itself. It's marked as a good first issue, with an example PR provided for guidance.

Complexity: 1/5

AI Summary: The uu_date utility in Rust incorrectly calculates the relative date for the pattern 'm9'. When given 'm9', uu_date produces a date that is one day later than the expected output from the GNU date command. This discrepancy, found via fuzzing, indicates an off-by-one error in uu_date's relative date parsing or calculation logic.
