This line should read

Code:
grep -ve '^#' -ve '^$' "$fIn" |\

of course.

The same in positive logic:
Code:
grep '^[^#]' "$fIn"

You are right. In fact i used "grep" here as a stand-in for my usual beautify-before-reading-process which looks like this ("<b>" is blank, "<t>" is tab):

Code:
sed 's/#.*$//
     s/^[<b><t>]*//
     s/[<b><t>]*$//
     /^$/d' "$fIn" | ...

This filters out all leading/trailing whitespace, removes comments and removes blank lines. Because i like to annotate my configs or workfiles extensively and i like to format them so that they are (for me) easy to read i need some preprocessing to remove the (for a script superfluous) extra parts in my loops.
