Well, no. AFAIK, >&- means to *close* the stdout file descriptor, while >/dev/null means to redirect (i.e. open) stdout to the /dev/null device. This is a lot of difference. > If it is, it must be with "df" as other programs don't complain. df is right to complain. It wants to output to stdout, but there is no stdout, so it can't output anything there. -- "One disk to rule them all, One disk to find them.
