[Xquartz-dev] Problem with redirection running wish script from Xquartz Menu

[Daniel Cote]

I don't execute that command from the command line I do it within a shell script so it only modifies a variable in the script. Since there is no way to pass parameters to a program from the Xquartz menu I write a script using utilities I have like my xprompt.tcl utility to gather the parameters needed for the program and then I start the program using the parameters I collected.

186,000 MPS isn't just a good idea, It's the law.

The tcl script simply puts up a window with a prompt and an entry widget where you type in an answer and allows you to repond and then it takes that response and writes it to stdout. The backquotes around the command cause redirection of stdout to the variable YEAR.

>>> Can you be a little more specific about what you're trying to do?  What makes you think the problem is the redirection of stdout?  You mention redirection from the XQuartz menu and Finder, but your statement doesn't have any redirection, and I'm not sure what you're doing with Finder.
