code:kore

$ cargo build --release --package uu_rm

これだけでOK

code:rm1

$ target/release/rm --help

Remove (unlink) the FILE(s)

Arguments:

Options:

-f, --force ignore nonexistent files and arguments, never prompt

-i prompt before every removal

-I prompt once before removing more than three files, or when removing recursively.

Less intrusive than -i, while still giving some protection against most mistakes

--one-file-system when removing a hierarchy recursively, skip any directory that is on a file

system different from that of the corresponding command line argument (NOT

IMPLEMENTED)

--no-preserve-root do not treat '/' specially

--preserve-root do not remove '/' (default)

-d, --dir remove empty directories

-v, --verbose explain what is being done

-h, --help Print help

動作はした

う〜ん...???

features/fs.rs でいくつかミスってるのでこれは、feature flagを変えたらビルドできるかな？

なんかやってはいるらしい

まだ微妙って言ってる

起こってること

WASI版のFileInformationが実装されてない

いい感じで既存のcrate(nixとか)を使えないっぽい...

理屈の上ではwasiでもできそうだが...
