Note
Shutdown to reclaim resource
# Shutdown WSL to reclaim resource
wsl --shutdownInfo
Set new configuration
# Update new info for wsl2
[wsl2]

wsl --update
# Check the list subsystem running
wsl --list --running
# Set default linux distribution
wsl --set-default <Distribution Name>
# Shutdown the wsl
wsl --shutdown
# Terminate linux distribution
wsl --terminate <Distribution Name>
# List distribution you have on Window machine

Reference: StackExchange - PowerShell equivalent of curl - Invoke-WebRequest
You can use curl alias of command Invoke-WebRequest
# Use on curl style
curl -Uri "https://www.example.com/myfile.txt" -OutFile myfile.txt
# Use on altenative
Invoke-WebRequest -Uri "https://www.example.com/myfile.txt" -OutFile myfile.txtBecause the powershell output work really special, object-type I think so. Thus, you can use select-object to get the what actually you want, such as Content
# Output not raw string
Invoke-WebRequest -Uri https://www.google.com | Select-Object 'Content'
For expand the raw string, you can use -ExpandProperty flag like example
Invoke-WebRequest -Uri https://www.google.com | Select-Object -ExpandProperty 'Content'

Documentation: How to change file permissions on Windows via powershell / cmd?
To change and set permission of file or folder in powershell, you can use Get-Acl and Set-Acl
# Copy permission from dog --> cat
Get-Acl -Path "C:\Dog.txt" | Set-Acl -Path "C:\Cat.txt"Or we can use icacls to handle with same situation. Read more tutorial and explanation
# grant the group FileAdmins 'Delete' and 'Write DAC' permissions to C:\demo\example
icacls "C:\demo\example" /grant:r FileAdmins:(D,WDAC)If you want to create 400 permission for your ssh-key or readonly file for currently user, you can use
# Give current user explicit read-permission
icacls.exe $path /GRANT:R "$($env:USERNAME):(R)"
# Disable inheritance and remove inherited permissions
icacls.exe $path /inheritance:rCreate new file

There is more of stuff way for create new file, and one of popular is use New-Item
New-Item -Path "C:\Logs\NewLog.txt" -ItemType FileIn another, you can use Out-File or Set-Content
# Use Out-File
"Hello World" | Out-File -FilePath "C:\Logs\NewLog.txt"

Set-Content -Path "C:\Logs\NewLog.txt" -Value "Hello World"Find the string in documentation
If you want to find the same idea of grep in Powershell, you can try with. Read more at PowerShell equivalent to grep -f
# Use Select-String with regex pattern
ipconfig --help | Select-String -Pattern "/all"
# Use findstr function.
# Look the help of function
findstr /?
# Try to find include str
ipconfig --help | findstr /I all
# Uses specified string as a literal search string.
ipconfig --help | findstr /C:"/all"Command can be used
Get-Help
Use the Get-Help cmdlet to display the syntax of any PowerShell cmdlet
# Basic
Get-Help Get-Service
# List example
Get-Help Get-Service -Examples
# Search onl
Get-Help Get-Service -OnlineGet-Service
Helpful to know what services are installed on the system
# Basic
Get-Service
# Pick display name colume
Get-Service | select DisplayName
# Find some service with condition
Get-Service | Where-Object {$_.status -eq "stopped"}Get-EventLog
Actually use PowerShell to parse your machine’s event logs using the Get-EventLog cmdlet
# View Application event log
Get-EventLog -Log "Application"
# View Security event log (Admin)
Get-EventLog -Log "Security"Get-Process
Getting a list of available services, it’s often useful to be able to get a quick list of all the currently running processes
# Basic
Get-Process
# Get full process (parrent and child)
Get-Process -Name chrome
# You can use Get-Process with combine Stop-Process
Get-Process | Where-Object { $_.Name -eq "myprocess" } | Select-Object -First 1 | Stop-ProcessFormat-Table
Used to format any output as a table
# Format list of process with fit-size
Get-Process | Format-Table -Property Name, CPU, Memory -AutoSizeFormat-List
Output properties as a list, each on a new line
# gets services and lists each individually
Get-Service | Format-ListWhere-Object
Where-Object is one of the most important cmdlets to know, as it enables you to take a dataset and pass it further down your pipeline for filtering
Get-Service | Where-Object {$_.status -eq "stopped"}For-Each
The ForEach-Object cmdlet performs an operation against every item in a specified group of input objects.
Get-Process | ForEach-Object {Write-Host $_.name -foregroundcolor cyan}Compare-Object
Useful to be able to compare two objects directly
Compare-Object "as" "ax"Select-Object
The Select-Object cmdlet selects the specified properties of a single object or group of objects.
Get-Process | Sort-Object name -Descending | Select-Object -Index 0,1,2,3,4Get-Member
One quality that makes PowerShell so versatile is that almost everything in PowerShell is an object consisting of a name, methods, and properties
Get-Service | Get-Member
Get-ChildItem
Get-ChildItem returns all the items in one or more containers
# Basic
Get-ChildItem .\content\
# Filter and include with folder
Get-ChildItem C:\Temp\* -Recurse -Include *taco*.txtOut-GridView
PowerShell output returns to the console window. However, if you need to interact with the output, you can use the Out-GridView cmdlet
Get-Process | Out-GridView
