Code:
while read line ; do
        echo $line | read a b c d


That will only work in ksh; to make it more portable:

Code:
while read a b c d; do

Code:
   if  [ "$x" = "$a" ] ; then


Where have you defined $x?

Code:
           ( IFS=-
           printf ' 1\n 1\n 0\n 0\n'
           printf ' %s\n' $b
           printf ' 1\n 7\n 0\n'
          printf ' %s\n' $c

# if $b (second row in the text file below) is > 1, I want the code


Do you mean second column?

Where do you test that condition? I don't see it anywhere.

Code:
# to go to the next line and print the $c and increment a counter

You don't increment a counter anywhere.

What is "$LOTO"/bin/loto_tsim?
