Jan 10, 2016 Well Powershell is a new console (like the CMD) based on.NET. It was created to have a native Windows console with more features that the old CMD doesn't provide. In Mac you may not need Powershell because the Bash is very powerfull yet, but its. PowerShell, the framework developed by Microsoft for systems management and task automation, went open source on August 18, 2016. The announcement detailed plans by Microsoft to extend PowerShell.
To install PowerShell on a Mac, just double-click the downloaded.pkg file. It will launch a package installer and install PowerShell like any other application. At the moment, the package doesn’t appear to be signed, so you’ll have to bypass Gatekeeper to install it. Change MAC Address In Windows With PowerShell Script ps2 over 8 years ago Here is a simple little PowerShell script for changing MAC addresses from the command line. The core PowerShell was just open sourced today Aug 18 2016, and now cross compatible on Mac OS X and Linux. Today I take a look at using PowerShell on Mac OS X Skip navigation.
As a mobile developer 90% of the time I work on a mac. Visual Studio for Mac is an awesome tool to create Xamarin mobile apps. More than not mobile apps are using services. You can use .NET Core to create APIs but deploying them isn't so easy on a mac. Sure you can use the Azure CLI, but if you are working with mixed teams Powershell seems to be king to deploy towards Azure.
About a year ago Microsoft made Powershell available for MacOs. But that doesn't mean you can use all of the Modules that are available. Until a few days ago you couldn't use AzureRM. Now that the AzureRM.NetCore is no longer in preview, it's time to explain how you can use the power of Powershell and AzureRM on your mac.
Installing Powershell
As I couldn't get the AzureRM modules working on an older version you need to make sure you run the latest version of Powershell for Mac.
You can download a .pkg package from https://github.com/PowerShell/PowerShell.
Installing is as simple as any other package. Just follow the wizard.

Installing is as simple as any other package. Just follow the wizard.
After installing the package you can verify the version of Powershell by opening a terminal window and start Powershell.
The version I have is v6.0.0-beta4. I couldn't make AzureRM work with version v6.0.0-beta3 so make sure you have at least version v6.0.0-beta4.
Installing AzureRM modules
Before installing modules you'll need to know in which directory you want to store your modules.
Open a Powershell and verify the path where you can store your modules
Open a Powershell and verify the path where you can store your modules
My path looks like:
Powershell For Mac Brew
I will store my modules in:
To install the AzureRM modules you'll need to open up a terminal and login as a root user. The instructions come from: https://www.powershellgallery.com/packages/AzureRM.Netcore/0.9.1
The path provided in the latest command corresponds with the path you found via $env:PSModulePath
Using the AzureRM modules
You can close the admin/root session and start a session as normal user.
Verify that the AzureRM modules are available
If you try to execute the Login-AzureRmAccount login command to login on Azure and start executing your scripts.
What if the AzureRM modules are not available?
When starting a Powershell session, not all modules are loaded to save memory. Depending on how you installed or stored the modules they won't be available by default.
So if the Login-AwureRmAccount is not available for you, you can auto load the AzureRm modules when starting a new Powershell session. You can do that by changing your profile.
Search for your profile:
My profile is located on:
If it doesn't exist you can simply create it.
You can simply import a module by adding 'Import-Module MyModuleName' in the file. Because AzureRM has multiple modules you can add them in one command
Authenticate to Azure via Powershell
Now you can authenticate via Powershell so can start executing the powershell scripts in your Xamarin solution.
Now open up a browser and go to https://aka.ms/devicelogin, provide the code that you got in your powershell session and you're good to go!
Conclusion
Microsoft made powershell and the AzureRM Modules available on MacOS. It will allow us to automate our backend deploys for our Xamarin mobile apps without switching to Windows.

This article describes the use of PowerShell scripting on Mac and Linux.
“PowerShell” refers to both the command-line shell and scripting language designed system administration.
PowerShell is an object-centered “management engine”that can be hosted in an application program.
- CMD in Windows
- PowerShell ISE (from Microsoft)
- PowerGUI
- SAPIEN Technologies PowerShell Studio
- Idera PowerShell Pro
ISE = “Integrated Scripting Environment” is a GUI that providespopup tab completion and other assists.
PowerShell promises more consistency than the various commands added over time by various parties.
- It reads Excel files natively as well as JSON, XML, and even ASCII.
- Microsoft Deployment Toolkit
- Microsoft System Center
- IBM, etc.
Open source on Linux and MacOS
From the PowerShell and DSC Team YouTube channel:
This 51-minute series of demos was published Aug 18, 2016, the same dayPowerShell is open-sourced for all OSs at
https://github.com/PowerShell/PowerShell.
https://github.com/PowerShell/PowerShell.
This article notes Desired State Configuration for Linux and the promise of SSH support arrived in 2014 (several months before Microsoft open sourced .NET and brought .NET Core to Linux). But “you had to author your scripts on the Windows platform, you had to configure things on the Windows platform and then deliver the desired configuration to a Linux box and have it be configured; now you can do all of that on Linux.”
Install PowerShell on MacOS

PROTIP: Know the PowerShell commands known not to work on Linux/macOS. - To leave PowerShell, it’s the same as in Bash scripts:exitWhen you return back in…
- Get help information for a command:get-help stop-service Inkscape for mac.
Visual Studio Code Editor
One text editor built for PowerShell is Microsoft’s Visual Studio Code.
- Install Visual Studio Code (see https://chocolatey.org/packages/VisualStudioCode):choco install visualstudiocode -y
- Install the PowerShell add-in to VSCode:choco install vscode-powershell -y
- Install the PowerShell Editor Services extension by pressing Ctrl+P, then type “ext install PowerShell” for a list of add-ins.Ctrl+P is the universal search that also does “fuzzy search” of text in files open.
- Click “install” of the extension named “PowerShell”.The icon turns to “installing”.
- Open a directory containing PowerShell scriptsand open the File menu and select “Open Folder …”.Select the folder containing your scripts.
The scripts show up in the Explore tab of the Side Bar.PROTIP: One advantage using VS Code is its Side Barenabling you to switch quickly among different files.Press Ctrl+B to hide and unhide the Side Bar. - Press Ctrl+ to open a new editor window.Up to three editor panes can be open at once.Press Ctrl+1, 2, or 3 to switch among the files.
- To edit user settings, press Ctrl+Shift+P, then type “user” and press enter.
- Click on “powershell.scriptAnalysis.enable”.
- Press Ctrl+Shift+<period> to change value from true to false or back again.
Keith Hill notesdebugging support provided by the PowerShell Editor Services extension currently runs only on Windows.
Install .NET Core
PowerShell is written on top of .NET.NET’s previous dependencies on Windows components have been removedin .NET Core.
PowerShell errors occur if .NET Core is not installed, so:
- Go to web page https://www.microsoft.com/net/core#macos
- The web page asks for OpenSSL to be installed.On a Mac:
- Click the link to download the 50.3MB
dotnet-dev-osx-x64.1.0.0-preview2-003131.pkghttps://github.com/dotnet/core/blob/master/cli/known-issues.md - Run the installer (for 106.3MB of space).
- Before installing anything or running through the update app, hit Command+i or pull down the File menu and choose “Show Files”:
- ./shared - Microsoft .NET Core 1.0.1 - Runtime
- ./host - Microsoft .NET Core 1.0.1 - Host FX Resolver
- ./dotnet
- ./sdk - Microsoft .NET Core 1.0.1 - SDK
These are folders within folder /usr/local/share under “Macintosh HD”. - Edit your Bash shell search PATH to include/usr/local/share/dotnetatom ~/.bash_profileAn example:
- Open a new Terminal shell window to run:The response:
- Paintbrush for mac free download. In a PowerShell invoke this to ensure that it can be done:
Execute script file
I like using script files rather than typing becauseit allows me to focus on the latest in what is usuallya long string of commands necessary in today’s complex world.
To call scripts, an example:
PROTIP: Make sure that when a file with .ps1 extension is clicked from Folder, the script is not launched to run, but that the script appears in a text editor.
A sample command to invoke the script including an execution policy :
Notice it’s “powershell” and not “powershell.exe” because Mac and Linux don’t recognize .exe.
When a script is signed, its location is locked to a specific full directory path, even when it’s in the current folder.
“remotesigned” is important because if this script has not been digitally signed, one needs to set PS execution policy to “RemoteSigned” (or “Unrestricted”) after reopening PowerShell as an Administrator to run:
By default PowerShell prevents the execution of PowerShell scripts on Windows systems.
Set-ExecutionPolicy RemoteSigned
Get a list of current security settings:
Get-ExecutionPolicy -List | Format-Table -AutoSize
See https://blog.netspi.com/15-ways-to-bypass-the-powershell-execution-policy/
https://github.com/MeshkDevs/InvokeTwitterAPIs
## Verify a signed script can be used #
- SetSet-ExecutionPolicy AllSigned
Install a signing cert on Mac
To add the CA root certificate (either PEM or DER format) into the OSX global keychain:
- Use Finder to navigate to your /System -> Library -> Keychains -> X509Anchors to your own Library -> Keychains.
- In a Terminal shell window, run command:certtool i mycertificate.crt k=X509AnchorsAdd a “d” at the end for DER format.
- Copy your Library -> Keychains -> X509Anchors back to /System -> Library -> Keychains.Use sudo.
Automatic logging
Increasingly, hackers are using PowerShell to create havoc.
So it’s a good idea to automatically logging using the
start-transcript
and stop-transcript
commands.BLAH: The sample script at https://github.com/wilsonmar/git-utilities/ps-auto-log.ps1,causes errors during execution of scripts.
Inside the file:
PROTIP: This can use up a lot of space quickly, so some management of its use is necessary.
Version Logic: If Then Else
I haven’t found a way to have a Bash script that can also be run as a PowerShell script.
PROTIP: Switching from Bash to PowerShell means a one-time migration and there is no turning back unless you want to maintainparallel scripts.
This is largely because of differences in if/then/else coding. The same if/then/else syntax in PowerShell scripts for Mac and PC is needed for the same script file to be used.
On Bash:
The question is whether a single PowerShell script can reallyrun on both Mac and Windows. Do a parallel run.
For different actions in PowerShell according to type of operating system:
NOTE: Because braces define actions, there is no “end if” (“fi”) in PowerShell.
Comparison Operators
-eq / -ne / -ge
-Like / -NotLike wildcard string - $name -Like “*sh”
-Match / -NotMatch regular expression - $name -Match “sh$”
-Contains / -NotContains a value in array - $name -contains “jo”
-In / -NotIn Is a value in an array - “joe” -in $name
Logical operators
-And
-Or
-Xor = Logical exclusive or.

Tilde and Providers
PROTIP: Use $home instead of the tilde (~)in PowerShell because tilde does not always represent the the user’s home folder as in Linux.This is because PS has different“providers” that include HKLM and HKCU top-levels in the Windows Registry.Get a list of providers and disk space:
Get-PSDrive
The response:
PowerShell calls files “items” as a term that groups files with registry keys and variables.
returns the Mode and LastWriteTime of the user.
Instead of “mkdir” to create folders, use
New-Item
Powershell On Linux
To list files in a folder, it’s the same as in Bash:
ls -al
PowerShell cmdlets (command-lets) enables computers to be managed from the command line,much like Bash shell scripts on Linux machines.How many are there?
(get-command).count
https://github.com/pester/Pester/wiki/Mock
Handling secrets
PROTIP: Files containing secrets, such as passwords andcertificates are NOT stored in GitHub nor script files, but in a separate location, and backed up among other local files.
The secrets are retrieved into the script at run-time.
See my tutorial on GitHub Data Security
Hash tables
BTW, keys in a hash table must be unique.
Hash tables are used throughout PowerShell.
An example of a REST API call:
Sort a hash tables using the GetEnumertor():
Objects
Get-Service m* | where {$_.status -eq ‘running’}
Get-Service m* | where status -eq ‘running’
Get-Service m* | where status -eq ‘running’
The “$_” represents the current object in v2 can handle more complexity than v3 syntax:
Alias not parameters
Many Bash commands work in PowerShell (ls, cat, echo) becauseAliases make many commands in Bash scripts work:
Free malware checker. get-alias echo
The response is “Write-Output”, which is what is executed.
BLAH: Many parameters to aliases are not recognized. For example, this common command results in an error:
ls -al
Instead, use:
dir -File | format-table
NOTE: dir is an alias to Get-ChildItem.
Thus,
Write-Host $env:computername -foreground Green
”–passthru” means do not go through Pipeline.
You can reset a default alias.
Environment Variables
PROTIP: Environment variables defined in Bash scripts can be read by PowerShell scripts and visa-versa.
Lists of environment variables:
The command “dir” is an alias of Get-ChildItem.
For the value of a single environment variable:
Get-ChildItem Env:USER
Get-ChildItem Env:AWS_DEFAULT_REGION
Get-ChildItem Env:AWS_DEFAULT_REGION
Paths
Instead of “rm -rf” in Bash:https://blogs.technet.microsoft.com/heyscriptingguy/2012/02/22/the-best-way-to-use-powershell-to-delete-folders/
“-WhatIf” specifies a dry-run.
Combine files
Ro add the content of several files into a single text file:
Cmdlets
PS has some smarter parameters, such as filtering for files onlyand running recursively into sub-folders:
dir c:work*.ps1 -file -recurse
All PowerShell cmdlets follow a standardized verb-noun naming convention that makes it easy to look up, find, and use cmdlets.For a list of all the verbs:
get-verb
REMEMBER: Capitalization counts within PowerShell.
get-command -verb export
get-command -noun ACL
get-command -noun ACL
paths
Only 25% of cmdlets are shipped with paths.
Strings
PROTIP: Don’t use “+” for string concatenation.
.NET Framework members
Initially built on Microsoft’s .NET Framework, PowerShell can refer to a static .NET member in square brackets with two colons to specify Pi:
[math]::pi
It’s wonderful that PowerShell doesn’t require an echo to display the value of objects.
To delete a file in the .NET I/O directory object:
The issue with using .NET objects is that they may execute in a different folder context than PowerShell.
TODO: $prompt
Other pre-defined variables
- To count the number of cmdlets:To get the current folder:Alternatively, use (since v2):This returns a PathInfo object.$scriptDir = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent
Dates
Based on http://ss64.com/ps/syntax-dateformats.html
Zip files using functions
Pipelines
Instead of just parsing text (as *Nix shells do),PowerShell works with objects in a pipeline.
Piping:
To list all variables defined and their values:
Get-Variable | Out-String
PROTIP: With PowerShell, it’s best to use out-file instead of “>” redirect character:
dir -file -hidden | out-file -filepath rootfiles.txt
Error handling:
Use preference variables for stream redirection:
1> Success 2> Error 3> Warning 4> Verbose 5> Debug
NOTE: Can Only merge to the success stream.
$Error is the automatic array that stores the last 256 exceptions (objects in error) - the default $MaximumErrorCount.
Error action preferences:
0 = Silently Continue
1 = Stop
2 = Continue
3 = Inquire
4 = Ignore [parameter value only]
1 = Stop
2 = Continue
3 = Inquire
4 = Ignore [parameter value only]
Module to call REST API
This suggests:
PROTIP: To press the trailing back-tick that breaks up a command into several lines, press the key at the upper left corner of the keyboard with your left hand while you press shift key using your right hand.
A space character is required before the tick.
PROTIP: Break up long text into a string block (which Microsoft calls here-string):
The output is:
From https://apps.twitter.com/ define a new app. In Permissions tab, select Read-only. Click Update Settings. In Key and Access Tokens tab, click “Create my access tokens”. Copy the Consumer Key (API key) and paste in ~/.passwords as TWITTER_TOKEN.
It takes many lines to mess with OAuth, so I make use of Adam’s library for Twitter’s v1.1 API described at:
http://www.adamtheautomator.com/twitter-module-powershell/
http://www.adamtheautomator.com/twitter-module-powershell/
- https://gallery.technet.microsoft.com/scriptcenter/Tweet-and-send-Twitter-DMs-8c2d6f0a
called “Tweet and send Twitter DMs with Powershell”.Adam’s “MyTwitter.psm1” I’ve download had 229 lines on 8/31/2014.PROTIP: The “.psm1” extension means it’s a PowerShell module.I used a text editor to edit the file to paste in variables for the 4 credentials from Twitter.I then saved the module in the same GitHub folder as my script,and added a command to pull the module into the script:Alternately, Copy-install the module to your $env:PSModulePathSee http://www.powershellgallery.com/gettingstartedPowerShellGet from the Windows PowerShell Framework 5.0The alternative is to put the module in the PSModulePath,which enables tab completion to complete the names of commands from modules that are not loaded.The module has these functions:- Get-OAuthAuthorization
- Send-Tweet
- Send-TwitterDm
- Paste in your PowerShell script:BTW, PowerShell cmdlets in https://github.com/Iristyle/Posh-GitHubis only for use on Windows.
