Hi Feneden,

the solutions using a simple regex suggested by Athanasius and haukex are great and definitely better than any solution using split and join (and I would have suggested exactly the same solution as haukex if he had not done it before).

However, I feel it might be useful for you to see how your original solution could be improved: 

use strict;
use warnings;
my @CPU_SPLIT = split /\s+/, $CPU;     # split the string on one or mo
+re spaces
# ~ s\ //g;                            # this line does not make any s
+ense to me, commented out.
my $result = join ' ', @CPU_SPLIT;     # join can operate directly on 
+an array, no need to list the indices
