How to read a file from bottom to top in Ruby?
- by two2twelve
I've been working on a log viewer for a Rails app and have found that I need to read around 200 lines of a log file from bottom to top instead of the default top to bottom.
Log files can get quite large, so I've already tried and ruled out the IO.readlines("log_file.log")[-200..-1] method.
Are there any other ways to go about reading a file backwards in Ruby without the need for a plugin or gem?
