[OS X TeX] Tex.mdimporter problem

[Eric van der Oord]

Thank you !

Alas, I guess there is no rapid  and safe beginner's way to modify metadata in the *tex files of some directories so that they can be found via Spotlight

The find command searches all directories of the TeX distribution up to the outermost leaf and passes all these directories' contents to apply which the mdls to each element. the first grep grabs for all occurrences of the word kMDItemContentType in the output of mdls. The egrep throws away all occurrences of the well-known kMDItemContentType's.
