💼 Career

Many IT and automation jobs require creating or updating files using PowerShell to manage systems and data.

1

Create text data variable

Create a variable called textData and set it to the string 'Hello, PowerShell!'.

PowerShell

# Create a variable called textData with the value 'Hello, PowerShell!'
# Your code here

Need a hint?

Use $textData = 'Hello, PowerShell!' to assign the string to the variable.

2

Create file path variable

Create a variable called filePath and set it to the string 'output.txt'.

PowerShell

$textData = 'Hello, PowerShell!'
# Create a variable called filePath with the value 'output.txt'
# Your code here

Need a hint?

Use $filePath = 'output.txt' to assign the string to the variable filePath.

3

Write text to file using Set-Content

Use Set-Content to write the content of textData into the file at filePath.

PowerShell

$textData = 'Hello, PowerShell!'
$filePath = 'output.txt'
# Use Set-Content to write textData to filePath
# Your code here

Need a hint?

Use Set-Content -Path $filePath -Value $textData to write the text.

4

Write text to file using Out-File

Use Out-File to write the content of textData into the file at filePath. This will overwrite the existing content.

PowerShell

$textData = 'Hello, PowerShell!'
$filePath = 'output.txt'
Set-Content -Path $filePath -Value $textData
# Use Out-File to write textData to filePath
# Your code here

Need a hint?

Use $textData | Out-File -FilePath $filePath to write the text.

5

Display file content to confirm

Use Get-Content to read the file at filePath and Write-Output to display its content.

PowerShell

$textData = 'Hello, PowerShell!'
$filePath = 'output.txt'
Set-Content -Path $filePath -Value $textData
$textData | Out-File -FilePath $filePath
# Use Get-Content and Write-Output to display the file content
# Your code here

Need a hint?

Use Write-Output (Get-Content -Path $filePath) to show the file content.
