Hi Yitzle:

Thank you very much for your suggestion:

Here is my perl file: clusters.pl

#! /usr/bin/perl
use warnings;
use strict;
while (my $line = <>) {
$line = ~/cluster\[(\d)+\] = {([\d ]+)}/ or die;
my @vals = split(/+/,"$1 $2");
print join(",",@vals). "\n";
}

my input file (clusters.in) is:

cluster[1] = { 1 2 3 4 8 10 12 13 14 18 20 22 }
cluster[2] = { 5 6 7 11 17 }
cluster[3] = { 9 15 16 19 21 23 27 30 31 33 34 }
cluster[4] = { 24 25 26 28 29 32 }

When I input to the shell

bash-3.00$ ./clusters.pl clusters.in > clusters.out

I do get the following error message:

Quantifier follows nothing in regex; marked by <-- HERE in m/+ <--
HERE / at ./clusters.pl line 6.

and got nothing written at the output file

Where am I making the mistake ?

Am I wrongly invocating the perl code ?

Thank you for any help

If you look carefully, the code I pasted and the code you pasted are
not the same.
On line 6, /+/ ought to be / +/ (a missing space) and on line 5, "=
~/" ought to be "=~ /"
.
