where [ exp ] and [ condition ] allow to detail operators....
anywhere you can have [ exp ] you can have ![ exp ] which means NOT exp.
while ![ $total -eq 0 ]
loop
is the same thing as
while [ $total -ne 0 ]
loop
Just like
IF [ A -GT 5 ]
DO X
ELSE
DO Y
FI
is the same as
IF ![ A -LE 5 ]
DO Y
ELSE
DO X
FI
Notice that the DO X and DO Y logic is swapped between the two cases.
