Creating log files for ruby code

Can you help me with this part?

how to write to an existing log file?
I used this to create a new one -
log = Logger.new(‘C:\Users\Dell\Desktop\my_logs.log’, 2, 1024 x1024)
log.info(“I’m an info log”)

Now, I want to write to this file from another ruby module, should I use the same line again? (log = Logger.new(‘C:\Users\Dell\Desktop\my_logs.log’, 2, 1024 x 1024))
