1. You need to create the wrapper first and may try it (after creating it) in terminal by typing "$HOME/bin/maxima“ 2. The wrapper should be placed in folder $HOME/bin (which is created first in case it doesn’t exist already by „mkdir“) 3. The snip surrounded two lines is the contents of the wrapper script - „8<" and „>8" are the two scissors :) To explain the terminal commands: The first terminal command is ensuring the existence of the folder „$HOME/bin“. The second one (starting with „cat“ and ending with EOF) is one the way to create the wrapper script without any editor. The third command is making your new wrapper script executable. The 2nd command needs to be entered exactly as you see it. You can verify what you did by using the terminal command: $ cat $HOME/bin/maxima It should give you the 2-line-script between the lines surrounded by the scissors. The problem why you has to do it yourself is: I cannot send you any shell script. No virus scanner will let it through. It doesn’t matter if it is useful or not. Regards, Stephan
