This is probably the best place to ask the question in its simplest form. I am writing a script which takes output of a command and puts it into a variable. After some debugging I figured out the command when it errors does not goto stdout but to the console (or wall). See example below:
When the command runs successfully
root@local# apcaccess status APC : 700 VERSION : xxxxx BATTSTAT : AC
When the command errors out
root@local# apcaccess status apcupsd @ localhost: Connection Refused. root@local# apcaccess status | grep -i version apcupsd @ localhost: Connection Refused.
I have noticed when I try to pipe the command through grep 'apcaccess status | grep -i version' I will get the version number on a successful run but on the system that it errors out on I get the error message. I believe it is not going through stdout.
The question is: how can I force the output to goto stdout?
