and modify text to command function to support this.
Shell builtins fail the binary command lookup test which result in a
WARN. Audit commands which include shell builtins must use the form:
"/bin/sh -c 'sh-builtin arg'"
So they are executed properly. Additionally Go will fail to execute
commands involving shell builtins if they are not in the above format.
This is caused by a command in the audit pipeline (for example
ps -ef | grep kube-apiserver) failing. The causes of this failure
in my testing is usually a missing config file.
Extensive refactor and correction in verification code to check for
config files and binaries.
Replace joncalhoun/pipes with implementation using exec.Cmds so errors
are visible and can be handled when audit pipeline commands fail.
Change some audit commands
from: ps -ef | grep <cmd> | grep -v
to: ps -C <something> -o comm,args --no-headers
which is simpler to work with.
