Is there a list of all the graphical applications' names so that I can start them from the command line in a terminal window?
A1:
No, there is no comprehensive list. You can find desktop applications mixed in with the programs in /usr/bin, /usr/local/bin, and /usr/X11R6/bin.
Q2:
When I use thexmessagecommand, I get an error message or an unexpected result. Why?
A2:
Remember to use the -buttons option and to enclose the comma-separated list of quoted button labels and the quoted message text as arguments.
Q3:
The sample Nautilus script won't work with files that have spaces in the filename. How can I fix this problem?
A3:
In the interest of keeping the script simple for illustrative purposes, we did not use techniques for accommodating filenames with spaces or other special characters. The website http://g-scripts.sourceforge.net/ provides freely copyable script code that enables Nautilus scripts to work with filenames containing spaces and other special characters.
