bug#55748: df: wrong column is checked in condition in total-verify.sh

[Daniel Hofstetter]

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
