logie17 has asked for the wisdom of the Perl Monks concerning the following question:
I have a list of file names such as the following:
Thanks in advance.
I'm doing a regex search to pull out the year, month, day and sorting like so:20070911.pdf 20070918.pdf
However the sort is choking (not sorting numerically) since it doesn't know how to deal with numbers like 01, 02, etc. Is there anyway in my regex to include just the number suffix if it's prefixed by a 0? (otherwise if it's not prefixed by a 0 include the prefix such as 12). I was messing around with (?<=..) extension, but I wasn't getting the results I needed. Any help would be truly appreciated and I hope my question was clearly defined.sort {$b->[3] <=> $a->[3] || $b->[1] <=> $a->[1] || $b->[2] <=> $a->[2 +]} map {$_ =~ m/(\d\d\d\d)(\d\d)(\d\d).pdf/;[$_, $1, $2, $3]} @files
Thanks in advance.
