This is very useful if you are creating a log file, or any file that should have a unique file name. If you run the batch file below it should print something like the following output: Today's date is 2009_10_21 The local time is 14_25_01 Date and time: 2009_10_21_14_25_01

The rest of this post will be left intact for historical purposes. ## If you were going to read the documentation… …then remove `--no-rdoc` and/or `--no-ri`. ## If you also want to update all installed gems… …then just say `sudo gem update`
