command line question

[joe at actionline.com]

Recently, Brian explained that I could add 2>/dev/null after a
command to eliminate the display of errors that occurs when I just
type gwenview filename.jpg.

gwenview filename.jpg 2>/dev/null

Thanks Brian. That is very helpful.

But I would still like to know what might be done to stop all the
error messages that the system generates when I just type gwenview
filename.jpg (as shown below).

Also, is there some additional option I could add to the example
script above that would cause the terminal window to close and leave
gwenview open?  As it is now, the terminal remains open and if I
close it, gwenview also closes.

Of course, I can open gwenview from the menu to avoid the terminal
window, but it would be helpful to be able to execute commands in
terminal (and create scripts for certain tasks) that I could execute
without leaving a terminal open.
