I want to further process two files so i wrote the code like this 

use POSIX;
use List::Util qw[min max];
use English;
use Getopt::Long;
use File::Basename;
use autodie;



my ($help,$csv_add, $csv_flex);

GetOptions (
            "csv_add=s"    => \$csv_add,
            "csv_flex=s"   => \$csv_flex,
            "help"         => \$help
           );

if ($help || !$csv_add || !$csv_flex )
{
  die "
Description: Provide the csv_add and csv_flex 

Usage $0
\t-csv_add <path> -csv_flex <path> : full csv file paths 
";
}

print "$csv_add\n";
print "$csv_flex\n";


open (CSVADD_FILE,"$csv_add") or die "Could not open $csv_add in read 
+mode OR there is no file with name $csv_add";
open (CSVFLEX_FILE,"$csv_flex") or die "Could not open $csv_flex in re
+ad mode OR there is no file with name $csv_flex";


#removing the spaces between the fields of csv

open(STDOUT, "+>csv_add_up");
rm_spaces(\*CSVADD_FILE);
close STDOUT;

open(STDOUT, "+>csv_flex_up");
rm_spaces(\*CSVFLEX_FILE);
close STDOUT;


#chomp removes any new line character at the end of line and can retur
+n number of elements removed
#remove spaces and /I/0 and /T/0 
sub rm_spaces {
    my $file = shift;
    while (<$file>) {
    chomp; 
    my @fields = split /,/; 
    s/\s+//g for @fields;
    s/\/I\/0//g for @fields;
    s/\/T\/0//g for @fields;
    print join ",", @fields,"\n";
}
}

Please suggest on how to make a single function that does the work of rm_spaces() and takes different files.
