Hi! I tried the "sort" function for a different thing I wanted to do, but it doesn't work as expected. 
my @confs = ();
push (@confs, $confs);

my @sortedconfs;

@sortedconfs = sort {$a cmp $b} @confs;
print @sortedconfs;
print "\n";

So I put all my conformations ($confs) in an array (@confs) and then I want to sort them numerically. However the output I get is only one file, the biggest number one, not a row of numbers sorted numerically. What do you think might be going wrong?

I'm also concerned by the fact that if I do "sort {$b cmp $a}" I get the same result as with {$a cmp $b}, shouldn't I get the reversed order? The variable $confs is my numbered chemical conformations, which is always 4 characters long in the style of B001, B002, B003 and so on. This variable is in my filenames along with other similar ones (similar to a filename like MOLEC1-B001-OPT-FREQ2), so I want to sort my files, according to their chemical conformations, numerically. But if I do "sort {$a <=> $b}" it complains that "it's not a numerical value", that's why I tried with cmp as seen here http://www.perlmonks.org/?node_id=259465. Any thoughts?

edit: I read a bit more and found that in mixed strings I should extract the numerical value and sort the substring, so I changed the previous "sort" line with "{ substr($a, 1) <=> substr($b, 1) }" but I get the same output :(
