kar_333 has asked for the wisdom of the Perl Monks concerning the following question:

hello monks

I am having problem in parsing the output from the CSV file. I want to add pipe symbol in between the character to do mutliple search similar to egrep

open(my $data, '<', $Config_File) or die "Could not open '$Config_File +' $!\n"; my $reg_exp; my $severity; my @fields=(); while (my $line = <$data>) { chomp $line; if(!$line =~ /^$/) { @fields = split "," , $line; $reg_exp = $fields[0]; $severity = $fields[1]; print $reg_exp; } } #print $fields[0]; #last unless defined $line; close($data) ;

current Output

service entered the stopped stateservice entered the running state

desired output

service entered the stopped state|service entered the running state

    Can you show us some lines of your input CSV-file?

    Use like the below it will parse the data and will create fields according

    $csv = Text::CSV::Simple->new({ sep_char => q{,}, binary => 1 }); $csv->field_map( qw( field1 field2 field3 field4 ) ); my @objectlist = $csv->read_file($file_name); foreach my $data (@objectlit) { print $data->{field1}."field2",$data->{field2} }

    You never introduce the | character. I would suggest replacing:
    print $reg_exp;
    with
    $accum .= "$reg_exp,";
    and then when ready to output your pipe delimited expression:
    $accum =~s/,$//; $accum =~ s/,/|/g; print $accum;
