Quite a useful command - very helpful with the transition to ASM. There were a lot of scripts that ran commands on the datafile filesystems, so we created a similar interface for ASM volumes that the scripts could use. FWIW, I think their asmdf command was very similar to <a href="http://oracledba.blogspot.com/2007/12/df-emulation-in-asm-asmbdf.html" rel="nofollow">this one from Yossi Nixon</a>.
