Takeaway: TechRepublic asked members to submit their favorite network administration scripts and this is one of the responses. You can use this script to generate a readable UNIX disk free listing.

TechRepublic recently asked members to submit their favorite Network Administration scripts for possible publication. One of the first to make a submission was Milton Ingram. For his effort, Milton earned $100 and the satisfaction of seeing his script published on TechRepublic.

Earn $100 for your admin script

Let us pay you for your original scripts so that we can publish them as downloads on TechRepublic and allow your fellow IT professionals to benefit from your scripting savvy. We only ask that you put in the appropriate comments to your scripts so that it's easy to tell what the script is doing and which variables might need to be customized. Send us your original admin scripts and we'll pay you $100 for each one that we publish as a TechRepublic download.

In their own words

This script is called df2 (See Listing A). Please excuse the Win line splits, it provides a more readable list of your Linux disk usage in Megabytes, which is really handy when you have a RAID attached with lots of disks. df -k never really cut it for me. It (df2) uses awk and should work on any UNIX variant. Everyone that sees it wants a copy. We use it all the time.
