“EasyBashGUI is a bash function library that aims to
give scripters simple GUI functions using kdialog, zenity, Xdialog
or (c)dialog depending on KDE or GNOME running or not, Xdialog
installed or not and, eventually, X server running or not (
(c)dialog is the minimum ).“So, if bash programmer write: “message ‘Thanks for using this
program’ ” he has not to worry in wich environment his program
runs. It’s enough at least (c)dialog installed, and program flow
will work as expected.”
