I suppose, the problem is, that “split” can't split to stdout. Maybe “dd” could be a replacement for “split” for getting chunks of data and then using the shell to compute file names with sequence numbers? tar ... | compress | ( # put a block size and number of blocks per file of your choice here: bs=1024k count=1024 # number of digits to be used for the sequence number: suffixlength=3 # put a filename prefix of your choice here: prefix= seqnum=0 test=test until { if ! "$test" "${#seqnum}" -le "${suffixlength:=1}" then printf >&2 '%s\n' 'The sequence numbers excede the suffix length.' test=: fi file="$( printf "%s%.${suffixlength}d" "$prefix" "$seqnum" )" { LC_ALL=POSIX dd ${bs:+bs="$bs"} ${count:+count="$count"} 3>&- | encrypt > "${file}" 2>&3 3>&- } 3>&2 2>&1 | { grep -F -q -x -e '0+0 records in' && cat ; } > /dev/null } do seqnum="$(( ${seqnum} + 1 ))" done ) As this problem is more one of split/dd/shell than of gpg, how about discussing this in the usenet group “comp.unix.shell” rather than in the “gnupg-users” mailinglist? _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
