*nix (UNIX and related) shells, and likewise the C programming language, which was designed for UNIX (and the syntactical descendants of C[2]) use the prefix 0x for numeric constants represented in hex:

Mr. Wizard
It's a prefix to indicate the number is in hexadecimal rather than in some other base. The C programming language uses it to tell the compiler "this is hex, not some meaningless letters and numbers."

0x[0-9|A|B|C|D|E|F]+ : Hexadecimal

0[0-7]+ : Octal

int Piano = (0xCDEFAB); // hexadecimal (0x..)

int Zero = (00); // octal (0..)

int JamesBond = (.007); // decimal (.xxx)
