vtl script fails when invoked with current directory having certain file names

[jim_fry]

When you have, for example, subdirectories in your current directory with filenames of a, b, and c, if you try to invoke vtl, you get the error message:

tr: too many arguments

Try 'tr --help' for more information

The problem lies in the bash script sampling.product . It has a line:

KERNEL_START=`${GREP} "${TEXT_START_TAG}$" ${KERNEL_MAP} | ${CUT} -f 1 -d " " | ${TR} [a-f] [A-F]`

When it is executed, [a-f] gets substituted with 'a b c b c', for some reason I'll let the bash experts explain.

I think it can be fixed with adding a backslash before the '['s and ']'s. There are other places in the scripts that may contain similar errors.

Thanks,
