see all the examples you have given are using cut but cut is the problem here.

The number 135 is stored as '13' '5F' or '5F' '13" (in packed decimal format) depending on whether is system is big endian or little endian.
To extract half of a byte to get '3' you need to display the field in hexadecimal as '1' '3' '5' 'F', which can be done using hexdump. Then use cut to extract the digit.

Ok, I get the issue here when the cut is printing it is printing the carriage return which is being displayed as { 0A} hex value. here is what I did. I captured the output of cut in a variable and displayed it using awk printf. this has solved my problem.

thank you all for all your time and effort.

very much apprectiate your efforts!!
