I have a large text file (>200MB). I want to read [n, n+a] bytes across all rows.
Suppose there are 1000 rows in the original text file. The output file would be 1000 rows.
What I know
head -c349 original.text|tail -c28 > output.txt. However, this only outputs one row. How can I
iterate though all rows?
Example: n = 2 a = 1.
