ファイルの内容を行番号付きで表示する
To display the contents of a file, use the cat command, but if you run it without options, it will simply display the contents. To display the contents of a file with line numbers, run the cat command with the option '-n'.
If you don't want to add line numbers to blank lines in the file, add the option "-b".
