how to overwrite the views output?
or you can simply add a views field 'Node:Link' - you can set the text in the options of that field.

If you want to add this field to other fields, choose the 'rewrite output' option of those fields, and place the token of that current field + the token of the 'node:link' field in the output area.

Make sure you check the 'exclude from display' option for the 'node:link' field and set the field first in the field order, so the token is made available
