I am running Nautilus 2.16.2 file browser in gnome 2.16.0 (RHEL 5.6 OS). I would like to associate a specific icon with every file that has the file type of .sas. I have found many references for associating an icon with a particular file, but I would like to apply this icon globally to all occurrences of any file that ends in .sas. How do I do this? More explicitly, there is a certain default icon associated with any .txt file that is created in the file browser. Where is this default icon located? Where is the file containing the command(s) that associate this default icon to any file ending in .txt? Thanks for any help.

I've found some more specifics for this but still don't have the exact steps to do this. The icon I want to associate with all .sas filetypes is located in a vendor directory, specifically /usr/SAS931/.../48/saspgm95.xpm. I can associate this xpm with each .sas file one at a time, but I need this to happen automatically any time a .sas file is created. Using root, I opened /etc/mime.types and added the line application/vnd.saspgm95 sas. I then copied the file /usr/SAS931/.../48/saspgm95.xpm to /usr/share/icons/gnome/mimetypes/48x48 and renamed the file from saspgm95.xpm to application-vnd-saspgm95.xpm. I logged out and logged back in and didn't see this icon associated with .sas files. Could someone point me to some instructions on how to properly associate a specific vendor's icon with files with filetypes .sas?
