Yes, it returns nonzero in ubuntu. I have tested it in centos before, it
returned zero same as your enviroment. I thinks it doen't relative to the
package version, because it also happened in netstat test. I considerd that
the default shell in ubuntu is dash not bash before, but it doesn't help
even I forced to use bash. Maybe it cause by the bash version or something
else, I could find the root cause yet. If you have time can you test it in
debian based distribution?
However, I gave by finger and bash package version below, it seems applying
some patch not pure packages.
