Hello Ron, the syntax used by "regcomp" should work. Nice features available in Oniguruma Regex or extended Regex are not supported.
See https://pubs.opengroup.org/onlinepubs/009696599/functions/regcomp.html https://pubs.opengroup.org/onlinepubs/009696599/basedefs/xbd_chap09.html for some additional information.
