{$:item.data_map.description.content.output.output_text|shorten(120)}
Use the shorten operator to put a maximum number of character to display. You will have to code the link for the Read More... manually after the display of the description.

Hi Mark: Thanks a million!I'm a new of EZ, so I still can't solve the problem. I want to let the Intranet file display like the below:
A linked file Submitted by On Date 3 lines of descriptionread more
my file_line.tpl is:
<div class="file_line"> <table > <tr> <td width=60%><h1>{attribute_view_gui attribute=$node.object.data_map.file}</h1></td> <td width=20% class="time">Submitted by {attribute_view_gui attribute=$node.object.data_map.created_by}</td> <td width=20% class="time">On {$node.object.published|add(21600)|l10n( datetime )}</td> </tr> <tr> <td colspan=3 width=100% class="intro">{$:item.data_map.description.content.output.output_text|shorten(120)}</td> </tr> </table> </div>
no matter what I changed in line 13, either display the whole distripution or display nothing.
would you please give me more advice?
Best Regards!sgpoon

Hi Mark!
I've solved the problem, just change the line 13 as below:($node.object.data_map.description.content.output.output_text|shorten(120)}
but i meet another problem: can't create a link just link a description of a file.
could you give me some help?
Regards!sgpoon

I think that there might be some syntax problems with the data_map calls, but unfortunately, I am not good enough with that to offer any sound advice.
Did you have it working at one point, but with the long version of the description? If so, I would get to that point, and just apply the shorten operator to that.

You would want to link to a new template that you would make that only displays the file description. (create a new template, set the override to display that content with the new template) However, it would probably be better to the a File display template which displays file name, full file description, download link, author, etc.) and make that the page that is linked from the Read More link.
