Article: Working Faster & Smarter with PowerShell

Windows PowerShellIt took a while but now a concise black-and-white version of my break-out session “Working Faster & Smarter with PowerShell” at last year’s PowerShell Conference 2017 in Singapore is online live exclusively for your reading pleasure!

Thanks to my good colleague Mitch Tulloch, a widely recognized expert on Windows Server and cloud technologies, for putting this together.

#pscore6 v.s. #powershell 5.x Modules (Part III)

You must have already noticed discrepancies in modules and corresponding commands[1] between PowerShell versions and releases. How can I keep abreast with constant changes in today’s ever fast-pace cloud technologies now that PowerShell is cross-platform commencing with version 6.x?

One way to find out yourself is illustrated here, paying attention to compare apples to apples i.e. Windows Desktop v.s. Windows Desktop. Otherwise, a big difference is to be expected between Windows Server 2016 and Windows 10 Desktop platforms running PowerShell 5.1.x for instance. Continue reading

#pscore6 v.s. #powershell 5.x Modules (Part II)

In the default installation of PowerShell Core 6.0 and Windows PowerShell 5.10 (PS5) with 13 and 89 modules discovered respectively, both PS versions have overlapping module names as illustrated:

CimCmdlets
Microsoft.PowerShell.Archive
Microsoft.PowerShell.Diagnostics
Microsoft.PowerShell.Host
Microsoft.PowerShell.Management
Microsoft.PowerShell.Security
Microsoft.PowerShell.Utility
Microsoft.WSMan.Management
PackageManagement
PowerShellGet
PSDesiredStateConfiguration
PSDiagnostics
PSReadline

An output with similar module names does not always mean that the number and type of commands in each of these modules correspond (see Part I of this blog series). Continue reading

#pscore6 v.s. #powershell 5.x Modules

Because of the cross-platform heterogeneous support design goal in #PsCore6, many platform specific #powershell functionality on the Windows operating system simply cannot, may not or have not yet been migrated over. Since Microsoft does not always fully document details of changes across product versions, this series of blog posts will attempt to identify any similarities and differences between these two PowerShell editions from the command perspective in a typical deployment, namely that of Windows PowerShell 5.x and the newly Release to Manufacturing/Web (RTM/RTW) GA version of PowerShell Core 6.0.0.

Let us kick start with the topic of Modules where the key functionality of PowerShell resides. Out of the box, executing powershell.exe (<= PS5.1) and pwsh.exe (PSCore6) will load a basic set of commands from core modules with exactly the same names:

ModuleType Version Name
———- ——- —-
Manifest 3.1.0.0 Microsoft.PowerShell.Utility
Script 1.2 PSReadline

Even though module names and versions carry the same information, Continue reading
