README

These are the scripts I used in my "Elementary Ruby Scripting for Sysadmins" Voonami Luau Presentation.

The initial script that all the others are based from, is one written by one of the Voonami NOC staff members as a learning exercise.  It checks a specified directory and issues either a warning or a critical error if the number of files in that directory exceeds a given threshold.

  Potential problems:
    Parameter parsing is non-standard, and just a little fragile
    File counting loop works, but there may be better ways to do it
    Minor logic error in the output section

revision_1

  Changes:
    Use OptionParser module
    Fix minor logic error in output section

  Problems
    File counting loop can still be tightened up

  minor revision a
  
    Changes:
      Move option parsing to a method
      
  minor revision b
  
    Changes:
      Tighten up file counting loop
      
revision_2

  Changes:
    Change file counting loop to "collect"
  
  Problems:
    Counts everything in the directory, even other directories
  
revision_3

  Changes:
    Change file counting loop to select, to account for directories

revision_4

  Changes:
    Alternative method of counting files.  Instead of using Ruby, we
    execute a shell command ("ls -aL | wc -l") and grab the output
    and use that.

    Probably not the most optimal way to solve this problem, but 
    does demonstrate how to do it.
