Full Discussion: PERL, extract value between double quotes

If you are attempting to pull the first field from each line within Perl, then you should probably open the file, and grab the variable in the following way (see the man pages for the open, split, and close commands in Perl).

Code:
#!/usr/local/perl
#
$myfile = "./methos";
#
#
        open OLDSHAD, "<$myfile" or die "Can not open methos\n";
        while (<OLDSHAD>) {
                ($usertmp, $everythingelse) = split(/,/, $_, 2);
                system("/usr/bin/echo \"$usertmp\" ");
        }
                close OLDSHAD;

Perl::Critic::Policy::Variables::ProhibitPerl4PackageNamUserpContributed Perl DocumPerl::Critic::Policy::Variables::ProhibitPerl4PackageNames(3pm)

NAME

       Perl::Critic::Policy::Variables::ProhibitPerl4PackageNames - Use double colon (::) to separate package name components instead of single
       quotes (').

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Perl 5 kept single quotes ("'") as package component separators in order to remain backward compatible with prior "perl"s, but advocated
       using double colon ("::") instead.  In the more than a decade since Perl 5, double colons have been overwhelmingly adopted and most people
       are not even aware that the single quote can be used in this manner.  So, unless you're trying to obfuscate your code, don't use them.

	   package Foo::Bar::Baz;    #ok
	   package Foo'Bar'Baz;      #not ok

CONFIGURATION

       This Policy is not configurable except for the standard options.
