Re: [9fans] sed oddity

[Uriel <uriel99@gmail.com>]

Interesting, this reminds me of a question I had: is there any command
that would read from stdin, and write to stdout, but if there was an
error when writing to stdout it would ignore it and continue reading
stdin? It is trivial to do it in C, but don't want to require an extra
program just to keep werc's error logs clean of spurious noise.

I guess based on what you said, that I might be able to use sed, but
only until your complaint is fixed :)
