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. initial_revision 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.
