Explain Octal and the linux command od + understanding 0x00

I'm trying to understand what this linux command does

ls | od -c

I know it's sending ls to od -c.

But what is od -c? What is a Octal and how is this useful?

This next question isn't relevant, but.. Since I'm at it, what's 0x00 , 0x01, 0x02....etc

Solution

  • od -c dumps C-style escaped characters, man od is your friend

    0x00 is hexadecimal number 00 (0x in C and many others indicate hex number)
