Code:
echo "hai this is for testing" | cut -b 4-7.

You can also use the above command to extract a range of characters from the string or from input file

Code:
IFS="\n"
for line in `cat input_file`
do
        echo ${line:5:5}
done

And also the above script will extract the characters from the 5th position up to the next 5 characters. Which means that it is extracting from 5 to 10 characters
