How can I check the version of packages to be installed with apt-get?

Question

I have the following output.

<tr id='row_27' valign='top'>
...
...

<td width="5%"><a href="http://localhost/daikon2/index.php/projects/admin/delete_log/6/6/27" class="deleteme"><img src="http://localhost/daikon2/assets/icons/delete.png"  alt="delete"  title="Delete Log" /></a></td>
</tr>

I want to get the last segments 27 in the href with JavaScript.

I tried the following but nothing happened.

var id =href.substring(href.lastIndexOf("/") + 1);
                        alert (id);

Solution 1

apt-cache show <packagename>

should include the full version numbers.

Solution 2

If you just want the version info without the description and such, use apt-cache policy instead of apt-cache show.
