The important thing is on what platforms your scripts need to run, now and in the future. The safest best is to limit yourself to only the POSIX set of features. These scripts should run practically everywhere. Another route would be to use ksh93 and its more advanced features but it might not be available natively on every platform your script needs to run on, so that would mean you would need to install ksh93, which should not be a problem since it has become open source and there are packages for many platforms…
