Grep reports 'write error' if the 'write' system call fails. If 'grep' was
incorrect, it's because the 'write' system call was incorrect. So, as near as I
can see this is not a 'grep' bug and I am closing the bug report.

Hi,

when we executed shell, we found that the grep command with wrong write error, and the return value was 2. May I ask where the problem is? And this is a probabilistic problem, Thank you
