in reply to Modifying a parameter to a recursive function

The only recursive call you have passes an array that you just declared and assigned in a minimal scope around the recursive call. The values you're modifying within the call are thrown away when that scope ends. It's not clear to me what you want to be modified. Do you expect $_->content_list() to return different values after the recursive call?

bellaire gave a good example of the sort of value-modification you seem to want.

[Corion]: Cosmic37: Ah, see perlfaq4, about How do I compute the intersection of two arrays
[Cosmic37]: I am out of practice; I use Perl for scientific programming for number crunching
[Corion]: Cosmic37: Basically, you read one file into a hash, keyed by your key, and then match the lines from the second file to that hash
[Cosmic37]: note that the two files only have datetimes which may match whereas other data per line is different format in file1 and file2 - is that really intersection?
[jedikaiti]: Hi Monks
[Corion]: Cosmic37: Well, if you want to use only parts of a line for the key, see split or whatever other mechanism to extract the key from the line
[Corion]: Hi jedikaiti!
[Cosmic37]: is there a webpage for full CB for this chat rather than side panel chat?
[Cosmic37]: thank you for advice
[Cosmic37]: peach greets jedi
