Leave out the quotes and the splats. As far as I can tell, the =~ operator
will match the target pattern (rds) anywhere in the search string. If you
need more context for the search target, you will need to add it explicitly.
if [[ ${hn} =~ rds ]]
should find rds anywhere in ${hn}. This for bash v3 and later, which
should cover you (bash --version tells all). The current version seems to
be 4 something,
