I had thought about making a script to do just this. For a while I had a page in HTML only that I listed some, but because it was a pain to edit I never really updated it. I finally realized I could just make a page in WordPress instead so here it is.
Remember that if you are running any mysql or mysqldump commands to not include the password when you type it in. This is because the commands you type into the command line are logged & thus if you type the password directly into the command it will be logged. If however you do not enter the password directly into the commands then it is not logged as it goes to the program. (This may vary depending on your installation, but I still feel it is a better idea to enter it after the command.)
Remember that Linux, Unix, & BSD are all case-sensitive. This is not like Windows or MD-DOS where things are case aware at best & may as well be case-insensitive as far as I care.
