Re: s6-log problem with +regex

Thank-you Guillermo & Laurent. I appreciate the detail, being a virgin
to daemontools this is a steep learning curve as I'm trying to ween off

The solution works nicely (& as intended) when using the workaround regex:

redirfd -r 0 /tmp/af
/usr/local/bin/s6-log n3 -.* +^a /tmp/a-only -.* +^b /tmp/b-only -.*
+^c /tmp/c-only -.* +^\\\[ /tmp/date-only f /tmp/default

However without any control directive, the result is:
s6-log: usage: s6-log [ -d notif ] [ -q | -v ] [ -b ] [ -p ] [ -t ] [ -e
] [ -l linelimit ] logging_script

Though running s6-log without a control directive is probably a little
silly, perhaps the requirement to have one may be worthwhile mentioning
in the doc.

Aside: I had orginally placed
ErrorLog "|/usr/local/bin/s6-log -b n32 s50000 S7000000
/var/log/httpd-error T !'/usr/bin/xz -7q' /var/log/httpd-error"
into apache24 which worked well in testing (one httpd), but of course in
production there are lots of httpd that do NOT use the parent for
logging errors, so locking is a problem.

Because I have three websites (3x error files, 3x access files) I was
looking at using 6 pipelines into two s6-log processes and regex's to
route the content. (hence my original example). Is this a good use of
resources or better to pipeline (funnel) to their own s6-log?

Kind regards, Dewayne.
