How to install sinhala fonts on ubuntu

First you have to download the font file "filename.ttf" to you machine.
Then you need some permissions to add those files to folder named
/usr/share/fonts/truetype
To do that first goto truetype folder by using following command

sanjeewa@sanjeewa-laptop:~$ cd /usr/share/fonts/truetype

Then use next command to grant file permissions to that folder(Else you wont be able to copy files to that folder)

sanjeewa@sanjeewa-laptop:/usr/share/fonts/truetype$ sudo chmod 777 ttf-sinhala-lklug/

Then copy your font file into folder named ttf-sinhala-lklug/

Then refresh browser

Change the order of window buttons and move side from left to right in Ubuntu 10.04

How to create mysql database with all permissions to users

Next command can use to grant all permissions to all users at given host here "% " sign denotes all

mysql> grant all privileges on DBNAME.* to "%"@"HOSTNAME" identified by 'PASSWORD';
