This is GREAT! It is also being dragged to my resource collection. You would be developing a really useful resource if you expanded this to 95% of the times you use other command line utilities, such as "find" (with and without "grep") Maybe such a thing exists, but I haven't found it.
Examples of real life application of these switches is very helpful.
Next, go read up on the rsync man page and play with it. Single most useful tool I think I've ever used to move data either within one computer or across the whole world. My favorite is:
# rsync -avSPe ssh user@sourcehost:/path/to/file user@desthost:/path/to/file
Cheers!
