comment Disabling a Button
but that would start disabled if b1 happend to have a value, for whatever reason. To be more robust one could test for something like: StringQ[b1]&&DirectoryQ[DirectoryName[b1]], which would also keep the button enabled if the user cancelles the file choose dialog. I think the most robust solution would be to use that test and still initialize with something well defined :-).

@user38498: I don't understand how an .exe (typically an executable program) and a .csv (comma separated values file format for tabular data) could replace one another? An executable can be used to do part of calculations outside of Mathematica, but .csv could only be used to store and load data you need for your calculation or generate with it. What is it that you want to do?

comment Wolfram Script Not Completing when ran as cron job
so if you throw away the sudo it works even with UseFrontEnd? Interesting but good to known. As for the answer: it is welcomed to self-answer on this site in cases like that, I'm happy if you do that.

I think it could also be good enough to unset the $DISPLAY environment variable, but I have no possibility to test that at the moment...

comment Wolfram Script Not Completing when ran as cron job
I was thinking about a real text console (what you typically get when pressing Ctrl-Alt-F1 on linux), not an emulation which runs as a window in a graphical environment. The point is that there you want no X server running that the script could access. When running from LXTerminal (or any other terminal emulation which is an X client) an X server be available. (note that you should add a @AlbertRetey when writing a comment to be addressed to me, otherwise I will not see it, see the small help link right to the comment field...)
