使用 ForkManager 在 Linux 上运行 Perl 脚本

Question

I am trying to run Perl script on my vps serer that it gets the Ip title of text-file where text-file is a list of ips. but i am getting this error :

 Use of uninitialized value $args[0] in pattern match (m//) at /usr/local/share/perl5/Parallel/ForkManager.pm line 73.
Missing required arguments: max_proc at ./get line 12.

where line 73 is if ( $args[0] =~ /^\\d+$/ ) { and line 12 is my $forkmanager = new Parallel::ForkManager->new("200");

my question is about how get this error fixed ? any help please

Answer 1

No way for us to know what $args[0] contains (or doesn't contain). Please provide a full code snippet where the error is reproducible.

As for the ForkManager error: First, try instantiating the ForkManager object with its newer Moose-style arguments, ie. my $forkmanager = Parallel::ForkManager->new(max_procs => 200);

Also note that using the new keyword is discouraged. From perlobj :

Outside of the file handle case, use of this syntax is discouraged as it can confuse the Perl interpreter. See below for more details.
