ubuntu日常操作

工作用电脑将会切换到ubuntu上了，记录下ubuntu常用操作。

===升级到php5.4===

For Ubuntu 11.10/12.04:

sudo add-apt-repository ppa:ondrej/php5

sudo apt-get update

sudo apt-get install php5

For Ubuntu 10.04 LTS, run the following commands (Thanks to Ivan Castellanos for the extra tip):



sudo echo "deb http://ppa.launchpad.net/ondrej/php5/ubuntu lucid main" >> /etc/apt/sources.list

sudo echo "deb-src http://ppa.launchpad.net/ondrej/php5/ubuntu lucid main" >> /etc/apt/sources.list

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E5267A6C

sudo apt-get update

sudo apt-get install php5

You can check if PHP 5.4.x is successfully installed with this command:



php5 -v
