how to automate an installation script suppressing user interaction
 

Hello All,

Im new to linux and this is my first post...

Im working on ubuntu and i need to install glassfish on my machine often. I want to write a script which can automate this installation and the post installation work so that I can run this script when i leave office and have everything done by the time I reach office the next day.

But after running the installation command there will be a license agreement which i need to accept by typing "A" at the console. Now How I can automate this so that the scipt can take this from a txt file? Please help.....


mv /home/liferay-portal-glassfish-linux-5.2.3.jar /opt/argon/
cd /opt/argon
java -Xmx256m -jar liferay-portal-glassfish-linux-5.2.3.jar

<Here The console expects to type "A" accepting the lisence agreement>

cd glassfish
chmod -R +x lib/ant/bin

This can be done using a program named expect. It takes some
time to learn, but it is worth it.
