Luckily, there's a simple command to automatically check, repair and optimize all tables in all databases when you're running a MySQL server on Linux / Unix / BSD.

mysqlcheck -u root -p --auto-repair --check --optimize --all-databases

That's all there is to it!

Basic vi Commands

What is vi?

The default editor that comes with the UNIX operating system is called vi (visual editor). [Alternate editors for UNIX environments include pico and emacs, a product of GNU.] 

The UNIX vi editor is a full screen editor and has two modes of operation:

1. Command mode commands which cause action to be taken on the file, and
2. Insert mode in which entered text is inserted into the file.

In the command mode, every character typed is a command that does something to the text file being edited; a character typed in the command mode may even cause the vi editor to enter the insert mode. In the insert mode, every character typed is added to the text in the file; pressing the <Esc> (Escape) key turns off the Insert mode.

While there are a number of vi commands, just a handful of these is usually sufficient for beginning vi users. To assist such users, this Web page contains a sampling of basic vi commands. The most basic and useful commands are marked with an asterisk (* or star) in the tables below. With practice, these commands should become automatic. 

NOTE: Both UNIX and vi are case-sensitive. Be sure not to use a capital letter in place of a lowercase letter; the results will not be what you expect.

To Get Into and Out Of vi

To Start vi

To use vi on a file, type in vi filename. If the file named filename exists, then the first page (or screen) of the file will be displayed; if the file does not exist, then an empty file and screen are created into which you may enter text.

To Exit vi

Usually the new or modified file is saved when you leave vi. However, it is also possible to quit vi without saving the file. 

Note: The cursor moves to bottom of screen whenever a colon (:) is typed. This type of command is completed by hitting the <Return> (or <Enter>) key.

Moving the Cursor

Unlike many of the PC and MacIntosh editors, the mouse does not move the cursor within the vi editor screen (or window). You must use the the key commands listed below. On some UNIX platforms, the arrow keys may be used as well; however, since vi was designed with the Qwerty keyboard (containing no arrow keys) in mind, the arrow keys sometimes produce strange effects in vi and should be avoided. 

If you go back and forth between a PC environment and a UNIX environment, you may find that this dissimilarity in methods for cursor movement is the most frustrating difference between the two. 

In the table below, the symbol ^ before a letter means that the <Ctrl> key should be held down while the letter key is pressed.

Screen Manipulation

The following commands allow the vi editor screen (or window) to move up or down several lines and to be refreshed.

Adding, Changing, and Deleting Text

Unlike PC editors, you cannot replace or delete text by highlighting it with the mouse. Instead use the commands in the following tables. 

Perhaps the most important command is the one that allows you to back up and undo your last action. Unfortunately, this command acts like a toggle, undoing and redoing your most recent action. You cannot go back more than one step.

The main purpose of an editor is to create, add, or modify text for a file. 

Inserting or Adding Text

The following commands allow you to insert and add text. Each of these commands puts the vi editor into insert mode; thus, the <Esc> key must be pressed to terminate the entry of text and to put the vi editor back into command mode. 

Changing Text

The following commands allow you to modify text. 

Deleting Text

The following commands allow you to delete text. 

Cutting and Pasting Text

The following commands allow you to copy and paste text. 

Other Commands

Searching Text

A common occurrence in text editing is to replace one word or phase by another. To locate instances of particular sets of characters (or strings), use the following commands. 

Determining Line Numbers

Being able to determine the line number of the current line or the total number of lines in the file being edited is sometimes useful. 

Saving and Reading Files

These commands permit you to input and output files other than the named file with which you are currently working.

vi – press escape to get into command mode if you re not already in command mode (if you are, it s OK to press it anyway). :q to quit :w to save, :wq to do both.

emacs – ^X^S to save, ^X^C to quit

Solution in Centos 5 and Fedora 9:

Through SSH:
yum search mbstring

yum install php-mbstring

/etc/init.d/httpd restart

INCREASE MYSQL MEMORY

vi /etc/my.cnf

After installing it took some time to login. I turned on Wifi and it worked. First it asked me to use headsets. I did not… So I could not hear the other side but they could hear me.

Plugged in the Headset and it worked. I also turned off the Wifi and still worked.  I am glad it works fine was at the point of installing Android on my HTC HD2. Lets hope now that Microsoft bought Skype it will run on MS and will be supported. Still dont understand why Skype is not supporting it anymore …

Only thing you should be careful with is your Data plan as the traffic may eat up your 200mb limit if you are not on a bigger plan

On April 10th my Amex card was hit with a fraudulent charge of 28 dollars then on April 19 another charge of 49.99.

This is what they posted on my amex:

TRANSACTION DESCRIPTION: PAYPAL *PROTEKTRADI 4029357733 CA
DOING BUSINESS AS: MARK PAYPAL
MERCHANT TYPE: INTRNT P2P CNSMR PMT
Transaction Date: Apr 10, 2011

Merchant Address: 2145 HAMILTON AVE SAN JOSE CA 95125-5905

I never authorized this transaction called Paypal customer service they said they will investigate 10 business days. Seems someone used your account and paid via “guest payment” where you only input the credit card number and address.

Not sure how my how my credit card information got out. I was always careful using it only time it gets out of my site is at a restaurant but still they dont know my address to use it on paypal….
I really suspect that some credit card information got stolen from some ” Securely stored brand company” as I never used my card with any small company. Just amazon, paypal or dominos…

Posting this article to remind you that you need to review your credit card statement thoroughly and if you see anything similar to the description above make sure you check that it is a transaction that you authorized.

Waiting for paypal to resolve this charge will keep you updated.

10 Days later Paypal issued AMEX a credit and I could see the credit 15 days later on my account. Had to cancel my credit card and get a new one.
