Redirect the "puts" command output to a log file
daemon, ruby
Solution
I should recommend to use ruby logger, it is better than puts, you can have multiple log levels that you can turn on/off: debug, warn, info,error, etc.
logger = Logger.new(STDOUT)
logger = Logger.new("/var/log/my-daemon.log")
I use runit package to manage ruby services, it has svlogd than will redirect daemon output to log file, here is run script for logger process:
#!/bin/sh
set -e
LOG=/var/log/my-daemon
test -d "$LOG" || mkdir -p -m2750 "$LOG" && chown nobody:adm "$LOG"
exec chpst -unobody svlogd -tt "$LOG"
Problem
I am working on creating a daemon in Ruby using the daemons gem. I want to add output from the daemon into a log file. I am wondering what is the easiest way to redirect `puts` from the console to a log file.
