Start applications with the default app from console

Its as simple as. Add this to your ~/.bashrc

alias open='nohup xdg-open >/dev/null 2>&1'

 Now you can start, for example a textfile, like this "open textfile.txt". Because of nohop in the alias you can even close the console session and the text editor stays open.
