In a view, how can I link a field to the node? In a fields view, the "title" field has a check box "Link this field to the original piece of content". But this check box isn't available for other fields. How can I achieve this functionality for other fields? 

E.g. in my case I have a custom "subtitle" field, and I would like to list the nodes subtitles. The subtitles should be links that point to the node.
as @Daphna mentioned and you can see here: drupal.org/node/1234862 you can use Content: Path field value as a token for the field you want to be linked to the content:


add Content: Path field and in the configure field modal box check Exclude from display to hide this field from being displayed and rearrange fields so this field is above the field you want to be linked to the content.
click the field you want to be linked to the content to open configure field modal box and in the Rewrite results section check Rewrite the output of this field.
in the opened textarea under Rewrite results write this: &lt;a href="[path]"&gt;[field_name]&lt;/a&gt;. you should replace field name with proper token of the field you want to be linked. you can find all the fields token in the Replacement patterns section under Rewrite results.
