My testing shows that the -f option just writes *from* logfile and not
*to* logfile. The output always appears in /var/log/messages.

Not sure if this approach will work for my purposes then.

It's not clear to me from the logger man page what -f is supposed to do,
but if you have control of /etc/syslog.conf it doesn't matter: simply
configure syslog to log to the file you want. Configure a facility (and
level if you want) in syslog.conf, and use that with the -p switch to
logger to log where you want.

The docs for the -f switch say:

-f file Log the specified file.

If I were writing the man page, and wanted to say that -f would send the
contents of file to syslog, I'd say "log the contents of the specified
file". Or, if I wanted to say that -f would send logs to the file, I'd
say "log to the specified file". I'm too lazy to dig up the source
code, so I don't know which of these -f is supposed to do. (My tests
didn't produce any interesting results.)

I'm pretty sure it is log *from*. My tests (on both syslogd and rsyslogd)
produce the same result. Contents of the file get dumped into
/var/log/messages.
