Say I need to write a script that will launch a terminal and execute a command and I need that to work on various systems. How can I do that in a safe and portable manner?
xterm always installed? I assume that any *nix with a GUI must have some terminal emulator. How can I get to it? Debian systems have
x-terminal-emulator but that, apparently, does not even work in Red Hat, let alone non-Linux *nixes.
