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 -         


        

Answer 1

I redirect stderr to stdout and then use grep's invert-match (-v) to exclude the warning/error string that I want to hide:

grep -r  * 2>&1 | grep -v "No such file or directory"
