Cat -v

wikipedia:cat -v

     -v      Display non-printing characters so they are visible.  Control
            characters print as ‘^X’ for control-X; the delete character (octal
            0177) prints as ‘^?’.  Non-ASCII characters (with the high bit set)
            are printed as ‘M-’ (for meta) followed by the character for the low
            7 bits.
