It seems about right. I think it should avoid the magic number 01777 as in cp. >Note that the actual behavior of >cp -p does NOT match the man page (more on this later). Note that mv across doesn't preserve the flags or nanoseconds field in the timestamps. `cp -p' preserves the flags if possible and rounds the nanonseconds field in the timestamps to the nearest microsecond (it can't do better since there is no way to set the nanoseconds field, and current file systems round to seconds or microseconds anyway). mv should be more careful to preserve things than `cp -p' Bruce
