cat in asm/ cat --show-all option
I'm rewriting cat in assembly, primarily to get better at asm, partially to make cat 50% smaller (or at least thats my goal, but cat is about 21000 bytes, it shouldn't be hard). Heres my questions. What exactly does the -A, --show-all option do? From what I can see, it just shows $ on new lines and ^I on every filled line. What exactly is this? I'm sure appending these values would not create the desired effect. Thanks in advance.
