Windows PowerShell Cheat Sheet

For a quick PowerShell scripting tutorial

ExecutionPolicy

• Get-ExecutionPolicy. Some possible policy levels:
  • Restricted: you can't run scripts. You can run only commands.
  • RemoteSigned: scripts written on the local computer can run. Scripts downloaded from the internet need to be signed by a digital signature from a trusted publisher.
  • Unrestricted: default execution policy for non-Windows computers and cannot be changed. Unsigned scripts can run.
  • Bypass: Nothing is blocked and there are no warnings or prompts.
• Set-ExecutionPolicy
  • Example: Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
  • -ExecutionPolicy parameter specifies policy. It's a good idea to use Default as the value. It sets the policy to Restricted on Windows clients and RemoteSigned on Windows Server.
  • -Scope parameter specifies scope of command. Some possible ones:
    • Process: Only affects the current PowerShell session
    • LocalMachine: This is default one. Execution policy affects all users on the current computer. It's stored in the HKEY_LOCAL_MACHINE registry.

Profile

• $Profile | Select-Object *: To see the profile types and the paths.
• New-Item -Path $Profile.CurrentUserCurrentHost: This will create profile script in the location.

Simple Commands For Scripting

• Creates a profile for current user

  New-Item `
  -ItemType "file" `
  -Value 'Write-Host "Hello <replace with your name>, welcome back" -foregroundcolor Green ' `
  -Path $Profile.CurrentUserCurrentHost -
  

• Create a script file New-Item -Path . -Name "PI.ps1" -ItemType "file"

• Open file in VS Code code PI.ps1

• Run script ./PI.ps1

• mv app webapp: rename app directory to webapp

• rm backup.zip: remove backup.zip
