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

Great Monks,

When I try to debug the CGI Code using the below code, I get unclear output in error_log file.

Code

my @arr=qw(Apple Banana Orange Flower Green Red Yellow); print STDERR @arr;

Unclear output found in error_log file

Thanks,

    Can you clarify the term "pretty view"? I find your log pretty informative.
    If you're using Apache web server you can customize log output with LogFormat directive.

      Hi arkturuz,

      Pretty view like "Apple Banana Orange Flower Green Red Yellow" in Single line.

      I am using Apache Web Server.

        print STDERR join(' ',@arr)
        should make it appear in one line in the Apache error log.

        You said you wanted to be around when I made a mistake; well, this could be it, sweetheart.
      If you're using Apache web server you can customize log output with LogFormat directive.

      You can modify the access log with LogFormat. You cannot modify the error log.

      From http://httpd.apache.org/docs/2.0/logs.html#errorlog :

      It is not possible to customize the error log by adding or removing information. However, error log entries dealing with particular requests have corresponding entries in the access log. For instance, the above example entry corresponds to an access log entry with status code 403. Since it is possible to customize the access log, you can obtain more information about error conditions using that log file.
        /me bows humble before the master :-)
        I admit, OPs question confused me, so I was rather too quick to answer.

    Try Data::Dumper
    use Data::Dumper; my @arr=qw(Apple Banana Orange Flower Green Red Yellow); print STDERR Dumper [ @arr ];
    gives you
    $VAR1 = [ 'Apple', 'Banana', 'Orange', 'Flower', 'Green', 'Red', 'Yellow' ];

    Have you tried printing a string rather than a list?

    print STDERR "@arr";
