The document outlines a PowerShell development workshop led by Bryan Cafferky, focusing on cmdlets, variables, aliases, providers, and drives. It includes lessons on using cmdlets and parameters, creating variables with different scopes, and managing aliases and PowerShell drives. The workshop aims to build knowledge progressively through a series of presentations and exercises.

User Created – These variables are created in the shell and in scripts and only
persist for the session. We can create variables in scripts with global, script, or
local scope.
Examples:
$name = “Bryan” # Declares and assigns a value to an untyped variable.
[int]$amount = 200 # Declares an integer type variable and assigns a value.](https://image.slidesharecdn.com/powershellworkshop2-150317105006-conversion-gate01/85/PowerShell-Workshop-Series-Session-2-11-320.jpg)

PowerShell Development Workshop 13
• Create untyped and assign a value in one statement.
$var1 = “some value”
• Create typed variable and assign value.
[string]$var1 = “some value”
• Create variable with cmdlet. Gives you greater control over properties.
New-Variable -Name var1 -Value "some value" -Scope private
• Assign value with cmdlet.
Set-Variable –Name var1 –Value “some value”
• Remove a variable with cmdlet.
Remove-Variable –Name var1](https://image.slidesharecdn.com/powershellworkshop2-150317105006-conversion-gate01/85/PowerShell-Workshop-Series-Session-2-13-320.jpg)

- 2. WORKSHOP FORMAT PowerShell Development Workshop 2 • Series of presentations and exercises that build on each other. • Start at the very basics and work up. • Webinar for all sessions. • GoTo Meeting Messages to ask questions.
- 3. GOALS OF THIS LESSON PowerShell Development Workshop 3 • Discuss cmdlets, pronounced command-lets. • Introduce some useful cmdlets. • Introduce PowerShell variables. • Discuss Aliases. • Discuss PowerShell Providers. • Learn about PowerShell Drives.
- 4. WORKSHOP LESSON 2: CMDLET REVIEW PowerShell Development Workshop 4 Is a single-feature command that manipulates objects in Windows PowerShell. You can recognize cmdlets by their name format -- a verb and noun separated by a dash (-), such as Get-Help, Get- Process, and Start-Service Are designed to be used in combination with other cmdlets "get" cmdlets only retrieve data, "set" cmdlets only establish or change data, "format" cmdlets only format data, "out" cmdlets only direct the output to a specified destination.. Each cmdlet has a help file that you can access by typing: get-help <cmdlet-name> -detailed Example: get-help write-host
- 5. WORKSHOP LESSON 2: CMDLET REVIEW: PARAMETERS PowerShell Development Workshop 5 Write-Host -Object "Good day!" -ForegroundColor DarkGreen -BackgroundColor Yellow Values passed to a cmdlet to control what it does. Parameter Name Parameter Values
- 6. WORKSHOP LESSON 2: CMDLET REVIEW: PARAMETERS - EXAMPLE PowerShell Development Workshop 6 Passing Parameters by Position Write-Host "Good day!“ Write-Host [-Object] [-NoNewline] [-Separator] [-ForegroundColor] [BackgroundColor] [<CommonParameters>] Passing Parameters by Name Write-Host -Object "Good day!" Parameter Name No Parameter Name
- 7. WORKSHOP LESSON 2: CMDLET REVIEW: COMMON PARAMETERS PowerShell Development Workshop 7 Parameters that are supported by all cmdlets. -Debug (db) -ErrorAction (ea) -ErrorVariable (ev) -OutVariable (ov) -OutBuffer (ob) -PipelineVariable (pv) -Verbose (vb) -WarningAction (wa) -WarningVariable (wv) * Aliases are in parentheses.
- 8. WORKSHOP LESSON 2: CMDLET REVIEW USEFUL CMDLETS PowerShell Development Workshop 8 Get-Help Get Help on a cmdlet. Read-Host Get user input. Write-Host Write to the console. Get-Member Display methods and properties of an object. Set-Location Set the current location for a provider. Get-ChildItem List the items within a collection. Export-Csv Write out a CSV file. Import-CSV Load a CSV file. Invoke-Item Loads the file using the application associated with the file's extension. Examples: scr_useful_cmdlets
- 9. WORKSHOP LESSON 2: VARIABLES PowerShell Development Workshop 9 • Types of Variables • Creating and Using Variables
- 10. WORKSHOP LESSON 2: VARIABLES PowerShell Development Workshop 10 User Created – These variables are created in the shell and in scripts and only persist for the session. We can create variables in scripts with global, script, or local scope. Automatic – These variables keep the state of the PowerShell session and can not be modified directly. The values of this variables change as we execute and use the PowerShell session. Preference – These variables store user preferences for PowerShell. These variables are created by PowerShell when a session is started and are populated with default values. We can change the values of these variables. Environment – These variables are the variables set by the system for Command and PowerShell environments.
- 11. WORKSHOP LESSON 2: USER CREATED VARIABLES PowerShell Development Workshop 11 User Created – These variables are created in the shell and in scripts and only persist for the session. We can create variables in scripts with global, script, or local scope. Examples: $name = “Bryan” # Declares and assigns a value to an untyped variable. [int]$amount = 200 # Declares an integer type variable and assigns a value.
- 12. WORKSHOP LESSON 2: USER CREATED VARIABLES PowerShell Development Workshop 12 [string] Fixed-length string of Unicode characters [char] A Unicode 16-bit character [byte] An 8-bit unsigned character [int] 32-bit signed integer [long] 64-bit signed integer [bool] Boolean True/False value [decimal] A 128-bit decimal value [single] Single-precision 32-bit floating point number [double] Double-precision 64-bit floating point number [DateTime] Date and Time [xml] Xml object [array] An array of values [hashtable] Hashtable object [object] Default type when no type specified.

- 13. WORKSHOP LESSON 2: CREATING VARIABLES PowerShell Development Workshop 13 • Create untyped and assign a value in one statement. $var1 = “some value” • Create typed variable and assign value. [string]$var1 = “some value” • Create variable with cmdlet. Gives you greater control over properties. New-Variable -Name var1 -Value "some value" -Scope private • Assign value with cmdlet. Set-Variable –Name var1 –Value “some value” • Remove a variable with cmdlet. Remove-Variable –Name var1
- 14. WORKSHOP LESSON 2: ALIASES PowerShell Development Workshop 14 • An alternate name for a cmdlet, function, or program. • Used to create shortcuts and easier to remember names for commands. • PowerShell has a number of predefined aliases. • Some emulate DOS or Linux commands. • We can create and maintain our own aliases with the following cmdlets. • New-Alias – creates a new alias. • Set-Alias – changes or creates a new alias. • Get-Alias – gets information about aliases. • Export-Alias – Saves aliases to csv file. • Import-Alias – Loads aliases from a csv file. Example: scr_alias.ps1
- 15. WORKSHOP LESSON 2: PROVIDERS PowerShell Development Workshop 15 • Allow us to interact with a resource as if it were a physical network drive. • Built-in providers include: • Alias • Variables • Registry • FileSystem • Function • Certificate • WSMan • To see a list of installed providers use the Get-PSProvider cmdlet. Example: scr_provider_demo.ps1
- 16. WORKSHOP LESSON 2: POWERSHELL DRIVES PowerShell Development Workshop 16 • Simulates a network drive mapping but can be to any PowerShell provider. • Is not limited to drive letters. Can be any name you want. • Do not persist beyond the PowerShell session unless you use the –Persist parameter. • Related cmdlets: • New-PSDrive • Get-PSDrive • Remove-PSDrive Example: scr_psdrives.ps1
- 17. REVIEW PowerShell Development Workshop 17 • What cmdlets are. • Parameters and some useful cmdlets • Creating and using PowerShell variables. • What Aliases are and how to use them. • What PowerShell Providers are. • What PowerShell Drives are and how to use them.
Editor's Notes
- #2: This template can be used as a starter file for presenting training materials in a group setting. Sections Right-click on a slide to add sections. Sections can help to organize your slides or facilitate collaboration between multiple authors. Notes Use the Notes section for delivery notes or to provide additional details for the audience. View these notes in Presentation View during your presentation. Keep in mind the font size (important for accessibility, visibility, videotaping, and online production) Coordinated colors Pay particular attention to the graphs, charts, and text boxes. Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale. Graphics, tables, and graphs Keep it simple: If possible, use consistent, non-distracting styles and colors. Label all graphs and tables.
