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?
