the code I have below sets out data as shown :

232      356      434      767      786      854      avg 571.50      group 0011100210
124      78      333      19      68            avg 124.40      

how do I change the code to make the output all of the above but on the one line:

232,356,434,767,786,854,avg1,571.50,0011100210124,78,333,19,68,avg2,124.40

so would that look like this in code to open data file and write to another file ?

use strict;
use warnings;

 

 
##### Open files

open(my $IN,"outvim2.vim") or die "Could not open input: $!\n";
open(my $OUT,">groupsort.vim") or die "Could not open output: $!\n";


my $Group_Min = 501;
my $Group_Max = 550;
my $Group_Count = 10;
 
my @averages = qw(571.50 551.50 551.17 531.17);
 
my @groups = (0)x$Group_Count;
foreach (@averages) {
        my $group = ($_ - $Group_Min)/$Group_Count;   #This calculates the group
        $group = 0 if $group < 0;    #In case you have a number below the expected min
        $group = $Group_Count-1 if $group >= $Group_Count;    #In case you have a number above the expected max
        $groups[$group]++;
}
 
print OUT join(", ", @groups) . "\n"
