Thank you, I will look at those (the page says they should be q{} and q{}
rather than q() and q()). It would still be useful for me to understand why my
combination of single and double quotes in the perl command does not work? Just
for "fun" I also tried concatenating the different strings in the perl command
with . which I understand is the perl string concatenation symbol but again to
no avail.
May I ask you what the correct way of including a literal $ in a substitution
string would be? In bash I would precede it with a single \ but that led to
loss of any text after that on that same line when used in the text string I
use in my perl command, neither did preceding it with \\ work.
I have seen that using an ENV() construct would work but I would prefer
something simpler, if at all possible.
I have used literal # in my substitution string without any problems but have
not gotten literal $ to work.
Thanks.
