Get-Member for object inspection in PowerShell - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the PowerShell cmdlet <code>Get-Member</code> do?

Get-Member shows the properties and methods of an object. It helps you understand what you can do with that object.

beginner

How do you use Get-Member to see the properties of a file object?

Use Get-Item <filepath> | Get-Member. This shows all properties and methods of the file object.

beginner

What is the difference between properties and methods shown by Get-Member?

Properties are details or data about the object (like name or size). Methods are actions you can perform on the object (like copying or deleting).

intermediate

How can you filter Get-Member output to show only methods?

Use Get-Item <filepath> | Get-Member -MemberType Method to see only the methods of an object.

beginner

Why is Get-Member useful when writing scripts?

It helps you learn what an object can do and what information it holds. This guides you to write correct commands and avoid errors.

What does Get-Member show about an object?

A Its properties and methods

B Its file size

C Its creation date

D Its content

Get-Member lists the properties and methods of an object, not specific file details like size or content.

Which command shows only methods of an object?

A Get-Member -MemberType Property

B Get-Item | Get-Member

C Get-Member -MemberType Method

D Get-Content

-MemberType Method filters Get-Member output to show only methods.

How do you inspect the properties of a file named example.txt?

A Get-Item example.txt | Get-Member

B Get-File example.txt

C Get-ChildItem example.txt

D Get-Content example.txt | Get-Member

Get-Item example.txt | Get-Member shows the properties and methods of the file object.

Which of these is NOT shown by Get-Member?

A Object methods

B Object events

C Object properties

D Object content

Get-Member does not show the actual content of an object, only its structure like properties, methods, and events.

Why might a beginner use Get-Member?

A To delete files

B To learn what commands work on an object

C To open a file

D To create a new object

Get-Member helps beginners understand what they can do with an object by showing its commands (methods) and data (properties).

Explain how Get-Member helps you understand a PowerShell object.

Think about what you want to know about an object before using it.

Describe how to use Get-Member to find only the methods of a file object.

Combine commands and use filtering options.

Practice

1. What is the main purpose of the Get-Member cmdlet in PowerShell?

easy

A. To execute a script block on an object

B. To list the properties and methods of an object

C. To delete an object from memory

D. To create a new object instance

Solution

1. Step 1: Understand what Get-Member does

   Get-Member shows the properties and methods available on an object, helping you explore it.

2. Step 2: Compare options with Get-Member purpose

   Options B, C, and D describe actions unrelated to inspecting object members.

3. Final Answer:

   To list the properties and methods of an object -> Option B

4. Quick Check:

   Get-Member = List properties and methods [OK]

Hint: Remember: Get-Member shows what an object has and can do [OK]

Common Mistakes:

• Thinking Get-Member runs code on the object
• Confusing Get-Member with object creation
• Assuming it deletes or modifies objects

2. Which of the following is the correct syntax to use Get-Member to inspect the properties of the output from Get-Process?

easy

A. Get-Process | Get-Member

B. Get-Member | Get-Process

C. Get-Process Get-Member

D. Get-Process > Get-Member

Solution

1. Step 1: Understand piping in PowerShell

   The pipe symbol | sends output from one command as input to another.

2. Step 2: Apply piping to Get-Process and Get-Member

   Correct syntax is Get-Process | Get-Member to inspect process objects.

3. Final Answer:

   Get-Process | Get-Member -> Option A

4. Quick Check:

   Pipe output to Get-Member = Get-Process | Get-Member [OK]

Hint: Use pipe (|) to send output to Get-Member [OK]

Common Mistakes:

• Reversing the order of commands
• Using spaces instead of pipe
• Trying to redirect output with >

3. What will be the output type when you run Get-Process | Get-Member -MemberType Property?

medium

A. List of properties of process objects

B. List of all processes running

C. List of methods of process objects

D. Error message about invalid syntax

Solution

1. Step 1: Understand the -MemberType Property filter

   This filter limits output to only properties of the object, excluding methods.

2. Step 2: Apply filter to Get-Process output

   The command lists only properties (like Id, ProcessName) of each process object.

3. Final Answer:

   List of properties of process objects -> Option A

4. Quick Check:

   MemberType Property = Properties listed [OK]

Hint: Use -MemberType Property to see only properties [OK]

Common Mistakes:

• Confusing properties with methods
• Expecting process list instead of members
• Assuming syntax error due to filter

4. You run the command Get-Process | Get-Member -MemberType ScriptMethod but get no output. What is the most likely reason?

medium

A. The -MemberType parameter is misspelled

B. The pipeline is missing before Get-Member

C. The objects returned by Get-Process have no methods

D. You used the wrong parameter value for -MemberType

Solution

1. Step 1: Check the -MemberType parameter value

   The correct value for methods is 'Method' (singular). Using a wrong value returns no results.

2. Step 2: Verify other options

   Options A and B would cause errors, not empty output. The objects returned by Get-Process have methods, so The objects returned by Get-Process have no methods is false.

3. Final Answer:

   You used the wrong parameter value for -MemberType -> Option D

4. Quick Check:

   Wrong -MemberType value = no output [OK]

Hint: Check exact spelling of -MemberType values [OK]

Common Mistakes:

• Using plural 'Methods' instead of 'Method'
• Forgetting the pipe symbol
• Assuming no methods exist on objects

5. You want to find only the properties of a service object that start with 'Status'. Which command correctly uses Get-Member to filter these properties?

hard

A. Get-Service | Get-Member -MemberType Property | Where-Object Name -like 'Status*'

B. Get-Service | Get-Member -MemberType Property Name 'Status*'

C. Get-Service | Get-Member -MemberType Property | Where-Object { $_.Name -like 'Status*' }

D. Get-Service | Get-Member -MemberType Property -Filter 'Status*'

Solution

1. Step 1: Understand filtering with Get-Member

   Get-Member does not support a -Name or -Filter parameter for partial matches, so filtering must be done after.

2. Step 2: Use Where-Object to filter properties by name

   Get-Service | Get-Member -MemberType Property | Where-Object { $_.Name -like 'Status*' } correctly pipes Get-Member output to Where-Object with a script block filtering names starting with 'Status'.

3. Final Answer:

   Get-Service | Get-Member -MemberType Property | Where-Object { $_.Name -like 'Status*' } -> Option C

4. Quick Check:

   Filter after Get-Member with Where-Object [OK]

Hint: Filter Get-Member output using Where-Object script block [OK]

Common Mistakes:

• Trying to use -Name or -Filter with Get-Member
• Using Where-Object without script block
• Filtering before Get-Member instead of after
