Thou shalt not take Stata's command names as thine own.

If you had bothered to type -help file- you would understand that your version of -file- will never be executed by Stata, as -file- is a built-in command. You could tweak Stata's directories (a very bad idea!) to occlude a command implemented as an ado-file, but a built-in command is just that.
