Why can't i match the pattern in this case?

 <tr>$
                                  <td nowrap valign="top" class="table_1row"><a name="d071301" id="d071301"></a>13-Jul-2011</td>$

i wo开发者_如何学编程uld like to match tr>$ <td nowrap valign, but when i try

grep -c "tr>\n<td nowrap valign" test.html

then i also tried

grep -c "tr>\n\s*<td nowrap valign" test.html

both of them find nothing. What error here?

One more question, can i add a character ^M into a html file by using sed???thanks

grep only does single line searches. Another source

To recap on some comments, sed does multiline searches and you can address the carriage return in sed syntax with \r

To add your control character, add the actual character: Type Ctrl+V, Ctrl+M.

sed will treat the control character just like a normal character.
