How to store a number along with the sign
If I use the below
cut -c37-48, the minus sign does not get appended to the number, as the sign is in the 36th Position.

But, If I use cut -c36-48, the minus sign appears infront of the number, but for positive numbers, it throws an error.

How can this be resolved..

You mean cut throws an error? Unlikely, so perhaps you could also post your script?

Code:
abc=`echo <filename> | cut -c37-48`

You're trying to cut a piece of the <filename> (as opposed to a piece of the file itself)?

Please show a part of the input file (filename), and such as it is, change your command to:

Code:
abc=$(cut -c37-48 filename)

Code:
while read each_rec
do
  fin_div_count=`echo "${each_rec}" | cut -c1-2`
  if [ ${fin_div_count} -eq 01 ]
  then
      abc=`echo "${each_rec}" | cut -c37-48 | bc`
