For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Microsoft windows - what version is running?

How do I find out things like the current version of Windows that I'm running from within a Perl program?

Posted by admin (Graham Ellis), 28 September 2003
The Win32 module that comes with the ActiveState distribution includes a lot of useful information ....

use Win32;

@bits = Win32::GetOSName();
print "Operating System:         $bits[0]\n";
print "Extra Information:        $bits[1]\n\n";

$timer = Win32::GetTickCount();
print "Milliseconds since boot:  $timer\n";

$who = Win32::LoginName();
print "Current User:             $who\n";

$drive = Win32::GetNextAvailDrive();
print "Next Available Drive:     $drive\n\n";

@fsinfo = Win32::FsType();
print "File System Type          $fsinfo[0]\n";
print "Maximum object name len:  $fsinfo[2]\n";
printf "Flags for file system:    %b\n",$fsinfo[1];

and here's the output from running that:

Operating System:         WinXP/.Net
Extra Information:        Service Pack 1

Milliseconds since boot:  43530153
Current User:             trainee
Next Available Drive:     E:

File System Type          NTFS
Maximum object name len:  255
Flags for file system:    1010000000011111111
