I like the idea, even if it works only with very recent Linux kernels. > Personally I use dd to move large files like disc images etc. > around, and I know I will not need the file cached. > > A very quick example patch which has only > been tested on linux is attached. > > Do you think this is required? > Do you think this is the right interface? There are two separate sets of data to which we might want to apply such an optimization: input and output. So how about an interface that lets the user disable caching on either or both? E.g., no-i-cache no-o-cache. I find the "-"-less options far less readable. Actually, I prefer the even longer names: input-cache-disable output-cache-disable nocache could still be an alias for the combination. _______________________________________________ Bug-coreutils mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-coreutils
