Answer file with filter or of type

[Michael J. Lew]

How do I successfully filter the file list in OS X?

The docs say I can use either filter or of type but I have to use 
four letter codes. "RSTK" works fine for rev stacks but "JPEG" does 
not work for files that the Finder declares to be of the kind "JPEG 
Image". How do I find valid codes?

I would like a filter for *.jpg and *.bmp files but all I am 
achieving at the moment is frustration.
