Re^2: System command using array and pipe

Bravo! Thank you very much. Your first solution worked like a charm.

I did have some trouble getting the second solution to work. Perl is complaining about "Use of uninitialized value $_ in pattern match (m//)" when the $backup_dir is passed to the sub text_to_shell_lit. I studied the text_to_shell_lit sub for a while and could not figure out what was wrong. (BTW, what is the underscore in the argument of the sub? ... Newbie question, I know.)

Fixed. The underscore prototype makes `$_` the default argument. Specifically, it makes `map text_to_shell_lit,` equivalent to `map text_to_shell_lit($_),`. I always forget I have to use `$_[0]` and not `$_` when I use the "`_`" prototype.	[reply] [d/l] [select]
