Thanks for the suggestion. I've never gotten around to using YACC or GNU Bison, surprisingly. I'll find some time to look into it. I know that both GNU Awk and Bash use Bison, so maybe I will have a look over there too. While looking around at Gnulib I also noticed the 'modechange' module. It seems fairly Coreutils specific, but implements the grammar listed in the POSIX specification for 'chmod' [1]. With all of these resources I am expecting to become a Bison expert in no time. :) [1] https://pubs.opengroup.org/onlinepubs/9699919799/utilities/chmod.html Collin
