[why] iozone can match the line like:

64 4 1599680 3057153 4274062 4897948 3588436 2892445 2772930 3057153 3958892 3057153 3022727 3363612 4564786

but cannot match the line as below(there are extra spaces after '2892445'):

64 4 1599680 3057153 4274062 4897948 3588436 2892445

[how] Add line.rstrip! before match

• line.rstrip! next unless line =~ /^\s*\d+.*\d+$/

for your update, there may be white space characters both at the head and tail of the line, avoid strip single side and reguler match the other side

update as: line.strip! next unless line =~ /^\d+.*\d+$/ or next unless line =~ /^\s*\d+.*\d+\s*$/

good idea!

Thanks, Kaiyi
