Disable warning messages in perl..
Hi All,
I'm not a perl programmer, so please help me to disable warning messages. I tried like commenting 'use strict' and 'use warning' in perl program. But it is not working.
All I want is to disable warning messages.
Please note its not actual ping program, But a perl wrapper for ping to display ping output in color (Cope).
Below is output:
Code:
$ ./ping google.com

Works fine when error redirected to /dev/null

Unfortunately, I cannot use output error redirection because all the perl programs are in PATH.
Actual ping perl program:
Code:
#!/usr/bin/env perl
use App::Cope;
use App::Cope::Extra qw[ping_time percent_b];
use Regexp::Common qw[net];
sub process {
# header
line qr{^PING (\S+)} => 'blue bold underline';
# ping replies
line qr{time=([0-9.]+ ms)\b} => \&ping_time;
mark qr{\($RE{net}{IPv4}\)} => 'blue';
line qr{(?:icmp_seq|ttl)=(\d+)} => 'bold';
line qr{^(?:\d+ bytes )?[Ff]rom ([^:\s]+)} => 'blue bold';
# final ping statistics
line qr{(\d+% packet loss)} => \&{ percent_b 0, 1, 26 };
line qr{min/avg/(?:max/mdev|ewma/max)\s=\s
([0-9.]+)/ # minimum
([0-9.]+)/ # average
([0-9.]+)/ # maximum or moving average
([0-9.]+\sms) # mean deviation or maximum
}x => ( \&ping_time ) x 4;
}
run( \&process, real_path, @ARGV );
Code:
$ head -n15 /usr/local/share/perl/5.20.2/App/Cope.pm
#!/usr/bin/env perl
package App::Cope;
#use strict;
#use warnings;
use 5.010_000;
