Is it possible to extract a few number of bytes out of a file using dd ? The file is located on a secondary drive.
I apologize if this is a simple question however I'm no pro at command line.

If this is
hello world how are you today
Then this would extract
dd bs=1 skip=6 count=5 if=file
It skips 6 bytes (
hello_), reads 5 bytes (
world), and ignores the rest.
bs=1 (or alternatively, when using GNU dd, using the count_bytes/skip_bytes flag), you can extract specific byte ranges at byte resolution.
