Object::ARGV を返します。
Object::ARGV を返します。
ARGF が ARGV をどう扱うかについては ARGF を参照してください。
例:
$ ruby argf.rb -v glark.txt
ARGF.argv #=> ["-v", "glark.txt"] -

self をバイナリモードにします。一度バイナリモードになった後は非バイナリ モードに戻る事はできません。
self をバイナリモードにします。一度バイナリモードになった後は非バイナリ
モードに戻る事はできません。
バイナリモード下では以下のように動作します。
* 改行の変換を停止する
* 文字エンコーディングの変換を停止する
* 内容を ASCII-8BIT として扱う
例:
# test1.png - 164B
# test2.png - 128B
# test1.png + test2.png = 292B
# $ ruby test.rb test1.png test2.png

そうでない場合、false を返します。
バイナリモードにするためには ARGF.class#binmode を使用します。
