Summary: C3 needs option to suppress STDERR
Initial Comment:
It would be really helpful in parsing output from cexec if I
could find a way to suppress the standard error from the
shell spawn. Take the following, for example. I first ran
a command, and had some shell spawn error on one
node. (ignore the error itself, as this is just an example).
I thought I could simply redirect error to /dev/null in the
command, but because the error comes from the shell
spawn, I have no control over it. Note the second
example. So if cexec had a "-nostderr" switch or
something, it would really be helpful.
thx

Turns out the err was coming before the shell invocation, and
ssh couldn't even prevent it... thus making it impossible for
c3. :(

i agree that making this a little easier would be good, i.e.
'--nostderr' is a good
idea but you can do this w/ the current tool using single
quotes, instead of
dbl quotes (get parsed by "first" shell).
# cexec -p 'hostname 2> /dev/null'
