我在這一行的時候，我從一個Ruby腳本內運行sed的一個問題工作：sed命令不是紅寶石內工作，但它在終端
sed -ne '/^<div class="results">/,/<\/body>/p' blah.html
我試圖內運行反引號``但它不能從Ruby腳本中正確執行。是blah.html的內容如下...

當我嘗試在Mac OSX上的終端相同的命令，它的工作原理沒有問題...
這是我得到時錯誤我嘗試從內紅寶石運行命令：
sed: 2: "/^<div class="results"> ...": undefined label 'ody>/p'
謝謝！修好了！非常感激！ – sambehera
