Those stderr messages would be coming from wc and NOT from ssh.
The OP's command should be
ssh user_foo@1.2.3.4 2> stderr.log "pgrep -f 'master_app' | wc -l"
You did not understand.
The ssh command is executed LOCALLY and it's stderr is on the local
machine.
So, the OP will divert the LOCAL stderr to a LOCAL file so that he can
see if the
LOCAL ssh command experienced any issues with the connection.
Capiche?????
I did understand. It doesn't matter if 2>file appears before the ssh
arguments, or at the end. In both cases, ssh's stderr will be written
to a local file. It is incorrect to say that the former example would
redirect wc's stderr, and not ssh.
