Using scripts

Because it is simple to implement, it takes time to consider potential anomalies.
The default is to use Jdk-6u45-linux-x64.bin(which is also exceptionally easy to replace), noting that scripts and installation files need to be placed in the same directory .
Paste the script into any text tool, select Jdk-6u45-linux-x64.bin, and replace all with your JDK version.

Using the example

Shell Code

# with no parameters

./installjdk.sh

# parameter is a normal user name

./installjdk.sh Newlinuxusername
