This persists whether the mode is interactive or not. My statement about "all but 7" was based on the flimsiest of conclusions: that restore would pick the files off the tape "as it went along". Using find -type f -print | awk 'END {print NR}' yielded considerably less than the 1444 files desired; "%&*#$%&(!", and other unpleasantries... SunOS (at least up to 4.1.3) supports an 'a' option for dump/restore to write a binary t.o.c. to somehow aid the selection process, but it appears to be supported only for local tape use. Whether this would have made any difference will have to wait... Apparently restore is designed to bring back only a handful of files or the whole thing efficiently; anything else wastes a massive amount of time. Comments, anyone? hth, larry
