This is just a collection of "common" functions on servers that may be performed infrequently enough to be easily forgotten.

Runs smartctl and prompts for the device to look at as well as greps through the output to display relevant statistics, since there's a lot of garbage in the output irrelevant to troubleshooting drive issues.
You can run ./smart_stats.sh /dev/sda and it will work, or ./smart_stats.sh and it will prompt you to provide the path to the disk.
