Installing Jython on Ubuntu

To install Jython with super user privileges:

sudo java -jar jython_installer-2.5.2.jar

Select /usr/local/lib/jython, then create a symbol link of Jython to /usr/local/bin:

sudo ln -s /usr/local/lib/jython/bin/jython /usr/local/bin/jython

If you have ubuntu 19.04, you can install with apt

sudo apt install jython

When you type in jython, the shell looks for a program with that name in the PATH. You should either call the program with its full path:

# ~ is an abbreviation for your homedir
~/jython2.5.2/bin/jython

or add the directory with the executable to your PATH:

PATH=$HOME/jython2.5.2/bin:$PATH

If you want the latter to persist across terminal sessions, add it to your ~/.bashrc.
