I don´t edit the "Setup.bash".
What is missing in the commandline, I don´t know.
The Setup.bash has this description:
Setup script for the ESO Scisoft scientific software collection
#
# This file should be sourced using the sh/ksh/bash dot "." command
#
# . /scisoft/bin/Setup.bash
#
# by all users of the software. They should be no need to do anything else.
Maybee I run a wrong command? By the way I added the path of the file in the
".profile-folder" like this:
# ~/.profile: executed by Bourne-compatible login shells.

if [ "$BASH" ]; then
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
fi

/home/klaus/scisoft/bin/Setup. bash

Scisoft as I see has many folders and softwares I think it´s a collection of
astronomy and about 1,1 GB.
I think Ubuntu cannot start them by my command, but I haven´t found another.
