Re: zsh: How to selectively filter stderr?
2008-09-16, 17:16(+00), kj:
Is there a way to filter some errors from a command's error stream
while leaving other errors undisturbed?
I know that, in zsh at least, I can do something like
% frobozz |& grep -v 'error to discard'
But this has the effect of mixing up both stderr and stdout, which
I don't want to do. Is there a way to filter stderr error selectively,
without merging it with stdout?
[...]
{ frobozz 2>&1 >&3 | grep -v 'error to discard' >&2; } 3>&1
With any Bourne-like shell (like zsh).
