This is a script that will monitor the physical drives of any machines that you have in an input file. It will send out notifcations if the free space is below a threshhold that is defined by you.

Hi,

Script was monitoring only last entry in computerinstall.txt.

Changed line 29 cut char:  } and place  }  on line 42.

Now it's working perfect.

Needs some work. Paths and names for input and output files are hard coded as literals throughout the script.
