Hi, I thought I was fairly useful at regexes, until I met rsyslog. Which has me severely stumped. I am trying to parse a really simple string:
ncy-rest01-hel.example.com to extract the "nyc" part (i.e everything in front of the '-' ). Now, usually I would simply use: (\w*)-.* and point at the capture group. But nope, that won't match. Fine, I thought. Maybe: (\w*)-(.*) And specify the first capture group. But no. Basically, the only thing that halfway works is: (\w*) ...but the problem is that will also match: nope.example.com without a dash in the hostname. Which it should not (and thus trigger a nomatch). The regex checker is not explaining what is going on, and regex101 does not support things like ERE or BRE, so that's no help... ------------------------------------------------------------------- The information contained in this message may be CONFIDENTIAL and is intended for the addressee only.
