How to install Scala from the official Scala distribution? This is needed on a Linux release with older version of Scala in the repository, e.g. Fedora 12.

# wget
# sh ./ VER

First step, install and configure the Java environment of course.

Second, download the scala-2.9.2 package and decpress it:

# wget
# tar xf scala-2.9.2.tgz

# mv scala-2.9.2 /opt/

Set globally for all users to include the Scala-2.9.2 installed in their $PATH:

echo "export PATH=/opt/scala-2.9.2/bin/:$PATH" > /etc/profile.d/

Alternatively, the $PATH setting can be added by users to their ~/.bashrc.

After re-logon, the users can use Scala now.

I summarize these steps and put them together in a script:
