Hi,
I got doubt in Pattern matching, could you tell me how the following differs in action ??
if ( $line1==/$line2/ )
if ( $line1=~/$line2/ )
if ( $line1=~m/$line2/)
What is the significance of '~' in matching.
Thanks in advance

AppConfig::Sys(3) User Contributed Perl Documentation AppConfig::Sys(3)
NAME
AppConfig::Sys - Perl5 module defining platform-specific information and methods for other AppConfig::* modules.
SYNOPSIS
use AppConfig::Sys;
my $sys = AppConfig::Sys->new();
@fields = $sys->getpwuid($userid);
@fields = $sys->getpwnam($username);
OVERVIEW
AppConfig::Sys is a Perl5 module provides platform-specific information and operations as required by other AppConfig::* modules.
AppConfig::Sys is distributed as part of the AppConfig bundle.
DESCRIPTION
USING THE AppConfig::Sys MODULE
To import and use the AppConfig::Sys module the following line should appear in your Perl script:
use AppConfig::Sys;
AppConfig::Sys is implemented using object-oriented methods. A new AppConfig::Sys object is created and initialised using the
AppConfig::Sys->new() method. This returns a reference to a new AppConfig::Sys object.
my $sys = AppConfig::Sys->new();
This will attempt to detect your operating system and create a reference to a new AppConfig::Sys object that is applicable to your
platform. You may explicitly specify an operating system name to override this automatic detection:
$unix_sys = AppConfig::Sys->new("Unix");
Alternatively, the package variable $AppConfig::Sys::OS can be set to an operating system name. The valid operating system names are:
Win32, VMS, Mac, OS2 and Unix. They are not case-specific.
AppConfig::Sys METHODS
AppConfig::Sys defines the following methods:
getpwnam()
Calls the system function getpwnam() if available and returns the result. Returns undef if not available. The can_getpwnam() method
can be called to determine if this function is available.
getpwuid()
Calls the system function getpwuid() if available and returns the result. Returns undef if not available. The can_getpwuid() method
can be called to determine if this function is available.
