[AGKetzer-ALICE] Working from home with x2go

[Henri Pekeler]

I forgot one thing. x2go works with ssh connections. If you have an echo 
or something similar in your $HOME/.bashrc the connection might not 
work. A quick workaround is to include the following lines on the top of 
your .bashrc and / or .bash_profile:

# Test if we are in an interactive shell. If not (i.e. when doing scp or 
something) return.
# $- gives a string representing the bash options. i stands for 
interactive. This means, if it is not interactive the bashrc returns
[[ $- != *i* ]] && return

Best regards,
Henri
