Moving bytes in file by offset and length
Hi,
I'm looking for a way (other than C) to pull out a number of bytes in a Linux file for a giving length. for example:

file1 contains 2 records:
abcdefghijkl
mnopqrstuv
.....
so, I want to pull starting in byte 9 for a length of 8

file2 would contain:

ijkmnopq

Thanks
