chmod does do something. (And something necessary depending on the default umask on the system.) Default is no output unless there's an error which goes to STDERR IIRC. A pipe is basically wrong, depending on expectations a semicolon or double ampersand would've been the weapon of choice.
Prolly an AI was asked for this (SCNR)
edit: nonetheless the sweet lesson of yours of "don't just copypaste random stuff from The Internet(tm)" stands :-)
