Mastering Vi Common in just 10 minutes

I have just finished my Unix exam. I know somebody hates VI very much, because it is very hard to use. It is so command-line, something like that. But learning to use this editor is very useful because you never know when will you unable to use X-Window or when will you face with command-line configuration.

So, just easing you in. VI is an editor in Unix and Unix-like system. It is command-line-based and very easy to use. You can learn its basics in just 10 minutes. VI has two modes; command mode and insert mode. Command mode is where you put your command and insert mode is where you put your text. Easy!

How to switch between two modes

1. In VI editor, press ESC to switch command mode, and press ESC again to insert mode. If you’re not sure, always press ESC two times, it will always be command mode. You will hear the beep sound.

How to insert text

1. In VI editor, press ESC two times to command mode, and press “i” or “a” and then type your text. “i” is insert, “a” is append your text

How to delete your text

1. In VI editor, press ESC two times to command mode, and where the cursor is press “x” to delete the character you want.

How to navigate in VI

1. In VI editor, you cannot use arrow keys in your keyboard to up, down, left or right. So how?, In VI editor, press ESC two times to command mode, and press “h” to navigate left, “j” to go down, “k” to go up and “l” to go left.

How to save and exit in VI

1. In VI editor, press ESC two times to command mode and then press “:wq” to save and exit the program.

See how easy is that, but VI is more than this you can read its documentation or visit this

Subversion : subversion on ubuntu

So, I have just created my googlecode project. And I have to deal with subversion which is quite new for me. Anyway, basically, this topic I will present how to create your own repository in ubuntu. I recommended this book which is very good for anyone who is new to subversion.

Note : I am using ubuntu 8.04. This version is different from the others that it uses htpasswd instead of htpasswd2.

Step 1, install subversion

Step 2, install Apache2. I’m using this server to use WEBDAV and because it’s a very extensible web server.

Step 3, make your own repository locally

Step 4, Set configuration for apache2 subversion module. This step, you have to re-configure your apache. It’s a xml-like config file.

Modified the file to look like this. Everything you need to know about this file is in the file itself. Just for one thing. If you plan to use multiple repositories use SVNParentPath. But If you have only one repository use SVNPath instead

Step 5, You have two choices. One is Basic authentication, and SSL access.
In this topic I use Basic authentication. So, modified the same file dav_svn.conf

Step 6, Create user and password

Step 7, Reload the setting

So, now you should be able to access your repository via http://127.0.0.1/svn/${yours repository}
if you want to change your server name. just edit the file /etc/hosts
