How can I have grep not print out 'No such file or directory' errors?

Question

I\'m grepping through a large pile of code managed by git, and whenever I do a grep, I see piles and piles of messages of the form:

> grep pattern * -R -

Errors like that are usually sent to the "standard error" stream, which you can pipe to a file or just make disappear on most commands:

grep pattern * -R -n 2>/dev/null
