I stumbled across a fantastic project at Sourceforge this morning via rootprompt.org. Souptonuts is a repository of tips and techniques covering numerous topics from the Linux kernel to MySQL and across the programming and platform spectrum.
The MySQL tips were excellent and very useful for everyday maintenance and troubleshooting. Extensive example scripts are included and worth a browse.
The project provides text file downloads with detailed information and contact information to correspond with the project’s admin.
Other subjects include awk, sed, bash, Excel and C++.
