Dear Roman,
thank you for both suggestions.
By the way, can I ask why it is necessary to re-introduce the array
context by another pair of parentheses, if the expression already produces
an array value?
Or does the ${...:|...} expression produce a string which needs to be
parsed again? Would this cause problems if any of the path elements
contained a space in the file name?
Thank you,
Peter
