NuttShell での基本的な動作確認


デフォルト設定でのビルド で起動するところまで確認できたので、NuttShell で基本的なコマンドなどの動作を確認してみます。


コマンド

コマンドの一覧

help で準備されているコマンドの一覧を見ることができます。

nsh> help
help usage:  help [-v] [<cmd>]

    .              dd             ifdown         mv             source

    date           ifconfig       mount          sleep          

Builtin Apps:
    adc                iptables           nsh                telnet

“Builtin Apps:” より上に列挙されているものは NuttShell のビルトインコマンドです。
help commandName で使用方法を見ることができます。

nsh> help cd
cd usage:  cd [<dir-path>|-|~|..]
nsh> help timedatectl
timedatectl usage:  timedatectl [set-timezone TZ]
