Strange filetype naming when redering with radiance

As others already wrote, this is most likely a problem of the bash in
general not Radiance in particular.
I found this post related to "bash and question mark at end of file name":

BTW: According to your script you are calculating a grid of approx. 800000
points to create an image. This image is then filtered down to 1/10 of it's
size (8000 pixels). Couldn't save time and only render every 10th point in
every 10th row in the first place?

## rm -f images/grid2illum_level_4.pic

As mentioned in my prior mail the output of the first command is

Any ideas? This does not happen when I enter other similar projects.

Hi Per,

Can you post the contents of your shell script? That way people might be
able to provide more input.
