Bashでecho,catを用いてRubyコメントアウト

More than 1 year has passed since last update.
echo "__END__";cat

=>

hoge
fuga

END
hoge
fuga

逆に

echo "__END__"|cat

だと

=>

END
となりうまくいかない。

- echoコマンドの詳細まとめました【Linuxコマンド集】

"echoコマンドの基本動作
使い方は、次のとおりシンプルだ。

$ echo 表示するもの"

- 【初心者向け】Linuxパイプラインの使い方を詳しく!

"「パイプライン」とは少々難しく言うと、「コマンドの入出力をコマンドへ引き渡す処理」のことを指す。"

"例えば、fileAの中身を見たいとき、次のようにコマンドを打つ。

$ cat fileA"
