I've got a machine that until recently used a ludicrously inode-hungry tree structure containing half a million files where it should have had (and now has) a database. Now I want to delete the leftover files, but it occurs to me that I may be risking some sort of IO catastrophe. Is a niced "rm -rf" as safe as I'm going to get, or is it worth messing about with "while sleep 1 do stopafter..."? -- Justin B Rye - writing from but not for Datacash Ltd
