Excuse me if this is another answer in my face question: I have a simple program - in order to run it, I have to open a shell and type in the program name and arguments; it then opens a second shell or window depending on the arguments and runs - this is dosemu for the inquisitive a 'dos in a box' program to run dos legacy stuff.
I would like to create a simple executable script that I could place on my desktop to run this sequence. I can't figure out how. I've tried simply writing a one line file that contains the program and arguments, and making that executable, but that doesn't work. I think there's that extra step of invoking a shell first that has to happen. If I press alt-f2 and type in the program in the command window, that works, so how do I turns those two steps into one executable?

The first line of your file must be "#!/bin/bash" to invoke the shell. The Hash-Bang (#!) in the first two bytes act like a magic number to tell the loader to look for a (full path to) a program that will read your command. All you need is the two lines:
#!/bin/bash dosemu -whatever

2 things are possible:
a) Edit ~/.bashrc with an editor of choice and add an alias line. alias foo='xterm -e top' This as an example. You will have to source the changed .bashrc file by running . ~/.bashrc or source ~/.bashrc If you then enter "foo" (without quotes) either in the console, xterm or the starter box queried with Alt+F2, an xterm will open with top running in it.
b) You may create a shell script instead. First create a bin directory in your user home running "mkdir ~/bin". Use then an editor of choice and create a file inside new directory bin in your home directory called i.e. "dosinbox" with following 2 lines content: #!/bin/bash /path/to/dosemu further parameters Use the proper path to dosemu (though it might not be necessary) and the correct parameters you like to use with dosemu and your program. Once saved the file make it executable with "chmod 750 ~/bin/dosinbox". If you then call "dosinbox" either on console or by creating a starter (Gnome desktop right mouse button click) the commend will be executed.

Correction: aliases do not work from an application starter box invoked by Alt+F2.
