Question

我想只在每个http：行之后使用grep文本并将其写入文件。我有输出流的当前输出

<table style="margin: 5px 15px; 5px 20px;" align="center" bgcolor="#666666" border="0" cellpadding="3" cellspacing="1">
    <tbody><tr style="background: #04C1DE; font-family: Verdana; font-weight: bold; font-size: 18px;">
      <td style="width: 50%; padding: 5px;">
        Word
    </td>
      <td style="width: 20%; padding: 5px;">
        Author
      </td>
      <td style="width: 10%; padding: 5px;">
        Date
      </td>
      <td>Category</td>
        <td>Active?</td>
        <td>&nbsp;</td>
        <td>&nbsp;</td>
    </tr>
  </tbody>

    </tr>

  <?php
  $count = 1;
    $bgc = 0;


  while($row = mysql_fetch_array($sql))
  {
    if ($count > 100) break;
    echo '<tr style="background: ';
        if ($bgc==0) echo "#FFFFFF";
        else echo "#CFEBFD";
        $bgc == 0?$bgc=1:$bgc=0;
    echo ';">';
    echo "<td><a href=../../words/display_word.php?ID=$row[ID]>$row[Title]</a></td>";
    echo "<td>$row[Author]</td><td>$row[Display_Date]</td><td>$row[category]</td>";
    if($row[active])
    {
      echo "<td>YES</td>";
    }
    else
    {
      echo "<td>NO</td>";
    }
    echo "<td>$row[link_count]</td>";
    if($row[Title] != "")
    {
      echo "<td><a href=words_edit.html?ID=$row[ID]>Edit</a></td></tr>";
    }
    else
    {
      echo "</tr>";
    }
    $count++;
  }
 ?>

我目前没有greping的代码在

您可以使用grep -E：

grep -i -oE 'https?://soundcloud\.com[^[:blank:]]*'

    grep -i -oE 'https?://[^[:blank:]]+' | \
