Subject: Remove shell regex evaluation

Tests performed with `[[ ]]` are not supported in POSIX-compliant shell.
However, regex evaluation with the `=~` operator is a specific bashism
which has no direct counterpart in POSIX, so I wanted to handle these
cases in their own patch.

We can simply use grep to evaluate these tests instead.  The same regex
syntax is supported.
