# Description This updates all the positional arguments (except with `--features=dataframe` or `--features=extra`) to start with an uppercase letter and end with a period. Part of #5066, specifically [this comment](/nushell/nushell/issues/5066#issuecomment-1421528910) Some arguments had example data removed from them because it also appears in the examples. There are other inconsistencies in positional arguments I noticed while making the tests pass which I will bring up in #5066. # User-Facing Changes Positional arguments are now consistent # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting Automatic documentation updates
