Re: Another regex match question

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.

Regards,
Lutz

I saw a few threads from +5yrs ago but the suggestions don’t seem to work.  Also, I looked over the monit manual and the regex(7) man page but I am still not able to get a simple match working.  One thread suggests to modify the source code and recompile, but that does not seem to help (I downloaded and compiled monit version 5.34.4) .
