Officially, $(...) is part of POSIX; it's not a Bash-ism. https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html We USED to use $(...) in the test suite. But that was dropped because it turns out that /bin/sh on Solaris does not support that (at least, that was my memory). I am neutral about whether or not we should continue to support ancient shells. --Ken
