Yes. These are error messages. Where else does they should go to but the
standard error output? Isn't it the usual way of printing error messages?

For some reason are you running the whole script through `sudo'?

We could do send error messages to /dev/null but centos-art.sh script is
using /dev/stderr to report error messages. For example, when a file
doesn't have execution right centos-art.sh script prints an error
message telling you that, so you can fix the problem. If we don't do
such printing finding errors would be even harder, don't you think?
