path to WMI source code in perl CPAN (in command prompt)
The Windows Management Instrumentation (WMI) source code for Perl is available through the Win32::WQL
module on CPAN (Comprehensive Perl Archive Network). However, the source code for the WMI implementation itself is not part of the CPAN module. Instead, the module provides Perl bindings to access and interact with WMI functionality on Windows systems.
To install the Win32::WQL
module and use it to work with WMI in Perl, follow these steps:
Open the Command Prompt (on Windows) or Terminal (on macOS/Linux).
Install the
Win32::WQL
module from CPAN using thecpan
command (orcpanm
if you have it installed):bashcpan Win32::WQL
If you don't have the
cpan
command, you may need to install it first using:bashcpan App::cpanminus
Once the module is installed, you can use it in your Perl scripts to work with WMI. Here's a simple example:
perluse Win32::WQL;
# Create a WMI object
my $wql = Win32::WQL->new;
# Query WMI data
my $query = "SELECT * FROM Win32_OperatingSystem";
my $result = $wql->query($query);
# Display the result
foreach my $item (@$result) {
print "Caption: $item->{Caption}\n";
print "Version: $item->{Version}\n";
# Add more properties as needed
}
This script queries the
Win32_OperatingSystem
class and retrieves the caption and version information of the operating system.
Please note that Win32::WQL
provides a Perl interface to interact with WMI but does not contain the actual WMI source code itself. WMI is a Windows system component, and its source code is not publicly available.
Additionally, to use WMI from Perl, you need to have the necessary permissions and access rights on the Windows system where you are running the Perl script, as WMI typically requires administrative privileges to query certain information.
