DEVTOME.COM HOSTING COSTS HAVE BEGUN TO EXCEED 115$ MONTHLY. THE ADMINISTRATION IS NO LONGER ABLE TO HANDLE THE COST WITHOUT ASSISTANCE DUE TO THE RISING COST. THIS HAS BEEN OCCURRING FOR ALMOST A YEAR, BUT WE HAVE BEEN HANDLING IT FROM OUR OWN POCKETS. HOWEVER, WITH LITERALLY NO DONATIONS FOR THE PAST 2+ YEARS IT HAS DEPLETED THE BUDGET IN SHORT ORDER WITH THE INCREASE IN ACTIVITY ON THE SITE IN THE PAST 6 MONTHS. OUR CPU USAGE HAS BECOME TOO HIGH TO REMAIN ON A REASONABLE COSTING PLAN THAT WE COULD MAINTAIN. IF YOU WOULD LIKE TO SUPPORT THE DEVTOME PROJECT AND KEEP THE SITE UP/ALIVE PLEASE DONATE (EVEN IF ITS A SATOSHI) TO OUR DEVCOIN 1M4PCuMXvpWX6LHPkBEf3LJ2z1boZv4EQa OR OUR BTC WALLET 16eqEcqfw4zHUh2znvMcmRzGVwCn7CJLxR TO ALLOW US TO AFFORD THE HOSTING.

THE DEVCOIN AND DEVTOME PROJECTS ARE BOTH VERY IMPORTANT TO THE COMMUNITY. PLEASE CONTRIBUTE TO ITS FURTHER SUCCESS FOR ANOTHER 5 OR MORE YEARS!

Editing with Vi

What is Vi?

Vi is to Unix/Linux what Notepad is to Microsoft Windows. Vi is the default text editor used with Unix/Linux systems. The name Vi is short for the term Visual editor. Because Vi was made for Unix/Linux systems, it stands to reason that it would use a command line user interface.

Modes:

Vi has two modes:

  1. Command mode – Using commands to manipulate the text
  2. Insert mode – Entering text as you would any other text editor

Editing in Command Mode:

You can use the j, k, h, l keys to move curser down, up, left, right respectively. Or, you can just use the arrows on the number pad.

You have no mouse action using Vi, so here some moves to keep in mind.

$ - moves the curser to the end of line your curser is on
w – moves the curser to the beginning of the next word
b – moves the curser to the beginning of the previous word
/ - Find command (used to find whatever letters or numbers follow)

Let's get started with some basic editing

I want to change the word bright in the first sentence to fine. So, I will enter /br to find the first word that starts with br.

Now that I have the word I want to change, I will use the cw command to change the bright to fine.

Keep in mind that it will put you into insert mode, so, you will need to press Esc to go back to Command mode.

On line 7 lieis should be lie is. Notice there are two blank lines before the text at the top, so it is actually line 9. 9G command will get us to the right line.

You can press the w key to advance the curser one word at a time, or you can advance by a number of words like 7w.

From here you can use the cw command to change the the word lieis to lie is, or advance the curser with the l key, or right arrow key, to set the curser on i in is, press the i key to enter the insert mode and press the space bar. Remember to press Esc to exit the insert mode.

When you are done editing, don’t for get to save your work. There are several ways, but I usually use the :x which saves the file and closes Vi.
