Bash Shell 5.3 Released with New Command Substitution

Bash 5.3 chops fork overhead by running substitutions smack in the current shell. A godsend for those sweating tight loops and embedded systems. Plus, feast on the new GLOBORDER variable—it hands you the reins for pathname sorting precision. And to sweeten the deal, Readline 8.3 sprinkles in case-insensitive searching. Time to flex your scripting muscles.
