Google Colab で man コマンドを使う方法

Google Colab で、シェルコマンドを実行するには、先頭に ! をつけて実行し たいコマンドを書けばよいのでござるが、 "!man man" などとして も、 man コマンドは実行できない。以下のようなメッセージが表示されるで ござる。 


This system has been minimized by removing packages and content that are
not required on a system that users do not log into.

To restore this content, including manpages, you can run the 'unminimize'
command. You will still need to ensure the 'man-db' package is installed.

"unminimize" というコマンドを実行すれば、 man コマンドを実行 できるようになるようなので、試してみたでござる。 


This system has been minimized by removing packages and content that are
not required on a system that users do not log into.

This script restores content and packages that are found on a default
Ubuntu server system in order to make this system more suitable for
interactive use.

Reinstallation of packages may fail due to changes to the system
configuration, the presence of third-party packages, or for other
reasons.

This operation may take some time.

Would you like to continue? [y/N]

しかし、 "Would you like to continue? [y/N]" と聞かれて、そ の答えを待つ状態がずっと続いてしまうでござる。 "!yes | unminimize" とすればよいようでござる。

"!yes | unminimize" を実行すると、そのあとは man コマンドが 使えるようになるでござる。
