Hi, While looking at https://github.com/coreutils/coreutils/blob/master/tests/df/total-verify.sh I noticed the following lines and I think "$5" in the last line (line 38 in the source code) should be "$6" because there are six columns in the df output and '-' is in the sixth column of the row starting with "total".
# Recognize df output lines like these: # /dev/sdc1 0 0 0 - /c # tmpfs 1536000 12965 1523035 1% /tmp # total 5285932 787409 4498523 15% - /^(.*?) +(-?\d+|-) +(-?\d+|-) +(-?\d+|-) +(?:-|[0-9]+%) (.*)$/ or die "$0: invalid input line\n: $_"; if ($1 eq 'total' && $5 eq '-') Regards, Daniel
