How to delete unread (which is not important) mails of Gmail in one step.

I had almost 10k of unwanted unread mails in my gmail inbox which I always wanted to delete. Recently I was able to do that in just one step I'm sharing you how to do deleting in one step.....

Type "is:unread" in your search mail box (one located at top of your gmail), click search mail.

Then select "All" which will only highlight the 20 or so on your page.  However, once you select "all" it gives you an option of "select all conversations that match this search".  click this, it highlights all unread messages, and then you can delete them all at once.

“Could not reliably determine the server’s fully qualified domain name, using … for ServerName"

You might probably faced the same following error while you were restarting the Apache server on Ubuntu.
$ sudo /etc/init.d/apache2 restart
Restarting web server apache2            
apache2: Could not reliably determine the server’s 
fully qualified domain name, using for 
… waiting apache2: Could not reliably determine the
 server’s fully qualified domain name, using for ServerName
To fix that problem, you need to edit the httpd.conf file. Open the terminal and type,
$ sudo gedit /etc/apache2/httpd.conf
By default httpd.conf file will be blank. Now, simply add the following line to the file.
ServerName localhost
Save the file and exit from gEdit.
Finally restart the server.
$ sudo /etc/init.d/apache2 restart

Installing LAMP in Ubuntu/Linux Mint

Through this tutorial, you'll learn how to Install Apache, MySQL and PHP.
If you're a webpage designer or developer and use PHP, mySQL and Apache, you'll be needing these applications to be installed.


In this guide I will show you how to install a LAMP system. LAMP stands for Linux, Apache, MySQL, PHP. The guide is intended to help those who have very little knowlegde of using Linux.

We will not cover how to install Linux the L of LAMP, because Linux Mint is already installed in your computer.

Install Apache

To start off we will install Apache.
1. Open up the Terminal (Applications > Accessories > Terminal).
2. Copy/Paste or type the following line of code into Terminal and then press enter:
sudo apt-get install apache2
3. The Terminal will then ask you for you're password, type it and then press enter.

Testing Apache

To make sure everything installed correctly we will now test Apache to ensure it is working properly.
1. Open up any web browser and then enter the following into the web address:
You should see a folder entitled apache2-default/. Open it and you will see a message saying "It works!" , congrats to you! or something like that!

Install PHP

In this part we will install PHP 5.
Step 1. Again open up the Terminal (Applications > Accessories > Terminal).
Step 2. Copy/Paste or type the following line into Terminal and press enter:
sudo apt-get install php5 libapache2-mod-php5
Step 3. In order for PHP to work and be compatible with Apache we must restart Apache. Type the following code in Terminal to do this:
sudo /etc/init.d/apache2 restart

Test PHP

To ensure there are no issues with PHP let's give it a quick test run.
Step 1. In the terminal copy/paste or type the following line:
sudo gedit /var/www/testphp.php
This will open up a file called phptest.php.

Step 2. Copy/Paste this line into the phptest file:
<!--?php phpinfo(); ?-->
Step 3. Save and close the file.
Step 4. Now open you're web browser and type the following into the web address:
(It will show you the page that has all information about your php. If you have prior experience of installing php in some other OS, you must have seen this page.)
Congrats you have now installed both Apache and PHP!

Install MySQL

To finish this guide up we will install MySQL.
Step 1. Once again open up the amazing Terminal and then copy/paste or type this line:
sudo apt-get install mysql-server
Step 2 (optional). In order for other computers on your network to view the server you have created, you must first edit the "Bind Address". Begin by opening up Terminal to edit the my.cnf file.
gksudo gedit /etc/mysql/my.cnf
Change the line
bind-address =
And change the to your IP address.
(In Linux Mint 11, terminal itself asked to the set password, But if it doesn't follow the step 3.)
Step 3. This is where things may start to get tricky. Begin by typing the following into Terminal:
mysql -u root
Following that copy/paste or type this line:
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yourpassword');
(Make sure to change yourpassword to a password of your choice.)
Step 4. We are now going to install a program called phpMyAdmin which is an easy tool to edit your databases. Copy/paste or type the following line into Terminal:
sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin
After that is installed our next task is to get PHP to work with MySQL. To do this we will need to open a file entitled php.ini. To open it type the following:
gksudo gedit /etc/php5/apache2/php.ini
Now we are going to have to uncomment the following line by taking out the semicolon (;).
Change this line:
To look like this:
Now just restart Apache and you are all set!
sudo /etc/init.d/apache2 restart

Now make wonderful website and have fun!wink
Terminal scares the newbies, but here, you'll see how magical terminal or comand promt (whatever you call it) is.
And as Linux is very secure OS, it'll ask you the password again and again, on every administrative command. You'll have to type in your password many times, whenever terminal asks for it.
