WinAdmin PowerShell

  • NEVER store live .env files or credentials inside any skill folder.
  • .env.template files belong only in templates/ within a skill.
  • Store live secrets in ~/.admin/.env (or another non-skill location you control) and reference them from there.

Status: Production Ready Last Updated: 2025-12-06 Dependencies: PowerShell 7.x, Windows 11 Latest Versions: PowerShell 7.5.x, winget 1.x

Quick Start (5 Minutes)

1. Verify PowerShell Version

$PSVersionTable.PSVersion
# Should show 7.x (NOT 5.1)

If PowerShell 7 not installed:

winget install Microsoft.PowerShell

2. Set Up Environment File

Create .env in your admin directory (never inside a skill folder):

# Create .env from template (store outside the skill)
$adminRoot = if ($env:ADMIN_ROOT) { $env:ADMIN_ROOT } else { Join-Path $HOME ".admin" }
Copy-Item "templates/.env.template" (Join-Path $adminRoot ".env")
# Edit with your device-specific values
notepad (Join-Path $adminRoot ".env")

3. Verify Environment

# Run verification script
.\scripts\Verify-ShellEnvironment.ps1

Critical Rules

Always Do

  • Use PowerShell 7.x (pwsh.exe), not Windows PowerShell 5.1 (powershell.exe)
  • Use PowerShell cmdlets, not bash/Linux commands
  • Use full paths with Test-Path before file operations
  • Set PATH in Windows Registry for persistence (not just profile)
  • Use ${env:VARIABLE} syntax for environment variables

Never Do

  • Use bash commands (cat, ls, grep, echo, export)
  • Use relative paths without verification
  • Modify system PATH without backup
  • Run scripts without execution policy check
  • Create multiple config files (update existing ones)

PATH Configuration

Check Current PATH

# View full PATH
$env:PATH -split ';'

# Check if path exists in PATH
$env:PATH -split ';' | Where-Object { $_ -like "*npm*" }

# Check User vs Machine PATH separately
[Environment]::GetEnvironmentVariable('PATH', 'User') -split ';'
[Environment]::GetEnvironmentVariable('PATH', 'Machine') -split ';'

Add to PATH (Permanent)

# Add to User PATH (no admin required)
$currentPath = [Environment]::GetEnvironmentVariable('PATH', 'User')
$newPath = "C:\new\path"
if ($currentPath -notlike "*$newPath*") {
    [Environment]::SetEnvironmentVariable('PATH', "$newPath;$currentPath", 'User')
    Write-Host "Added $newPath to User PATH"
}

# Refresh current session
$env:PATH = [Environment]::GetEnvironmentVariable('PATH', 'User') + ";" + [Environment]::GetEnvironmentVariable('PATH', 'Machine')

Common PATH Entries

# npm global packages
C:\Users\${env:USERNAME}\AppData\Roaming\npm

# Scoop apps
C:\Users\${env:USERNAME}\scoop\shims

# Python (winget install)
C:\Users\${env:USERNAME}\AppData\Local\Programs\Python\Python3xx

# Git
C:\Program Files\Git\cmd

Environment Variables

Session Variables (Temporary)

# Set variable
$env:MY_VAR = "value"

# Read variable
$env:MY_VAR

# Remove variable
Remove-Item Env:\MY_VAR

Permanent Variables

# Set User variable (persists across sessions)
[Environment]::SetEnvironmentVariable("MY_VAR", "value", "User")

# Set Machine variable (requires admin)
[Environment]::SetEnvironmentVariable("MY_VAR", "value", "Machine")

# Read from specific scope
[Environment]::GetEnvironmentVariable("MY_VAR", "User")

# Remove permanent variable
[Environment]::SetEnvironmentVariable("MY_VAR", $null, "User")

Load Variables from .env File

# Load .env file into current session
function Load-EnvFile {
    param([string]$Path = ".env")

    if (Test-Path $Path) {
        Get-Content $Path | ForEach-Object {
            if ($_ -match '^([^#][^=]+)=(.*)$') {
                $name = $matches[1].Trim()
                $value = $matches[2].Trim()
                Set-Item -Path "Env:\$name" -Value $value
                Write-Host "Loaded: $name"
            }
        }
    } else {
        Write-Warning "File not found: $Path"
    }
}

# Usage
Load-EnvFile ".env"

PowerShell Profile

Profile Locations

# Current user, current host (most common)
$PROFILE.CurrentUserCurrentHost
# Typically: C:\Users\<user>\Documents\PowerShell\Microsoft.PowerShell_profile.ps1

# View all profile paths
$PROFILE | Get-Member -Type NoteProperty | ForEach-Object {
    [PSCustomObject]@{
        Name = $_.Name
        Path = $PROFILE.($_.Name)
        Exists = Test-Path $PROFILE.($_.Name)
    }
}

Create/Edit Profile

# Create profile if not exists
if (-not (Test-Path $PROFILE)) {
    New-Item -ItemType File -Path $PROFILE -Force
}

# Edit profile
notepad $PROFILE
# Or: code $PROFILE (VS Code)

Recommended Profile Content

# PowerShell Profile
# Location: $PROFILE

# === ENVIRONMENT ===
$env:COLORTERM = "truecolor"

# === PATH VERIFICATION ===
$npmPath = "$env:APPDATA\npm"
if ($env:PATH -notlike "*$npmPath*") {
    Write-Warning "npm not in PATH. Add to User PATH via Environment Variables."
}

# === FUNCTIONS ===

# Load .env file
function Load-Env {
    param([string]$Path = ".env")
    if (Test-Path $Path) {
        Get-Content $Path | ForEach-Object {
            if ($_ -match '^([^#][^=]+)=(.*)$') {
                Set-Item -Path "Env:\$($matches[1].Trim())" -Value $matches[2].Trim()
            }
        }
    }
}

# Quick navigation
function admin { Set-Location "${env:ADMIN_ROOT}" }

# === ALIASES ===
Set-Alias -Name which -Value Get-Command
Set-Alias -Name ll -Value Get-ChildItem

Execution Policy

Check Current Policy

Get-ExecutionPolicy
Get-ExecutionPolicy -List  # Shows all scopes

Set Execution Policy

# For current user (recommended)
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

# Options:
# - Restricted: No scripts allowed
# - AllSigned: Only signed scripts
# - RemoteSigned: Local scripts OK, downloaded must be signed
# - Unrestricted: All scripts (warning for downloaded)
# - Bypass: No restrictions, no warnings

Bypass for Single Script

powershell -ExecutionPolicy Bypass -File script.ps1

JSON Operations

Read JSON

# Read and parse JSON file
$config = Get-Content "config.json" | ConvertFrom-Json

# Access properties
$config.propertyName
$config.nested.property

# Access array items
$config.items[0]

Write JSON

# Create object and save as JSON
$data = @{
    name = "value"
    nested = @{
        property = "value"
    }
    items = @("item1", "item2")
}
$data | ConvertTo-Json -Depth 10 | Set-Content "config.json"

Modify JSON

# Read, modify, save
$config = Get-Content "config.json" | ConvertFrom-Json
$config.propertyName = "new value"
$config.newProperty = "added"
$config | ConvertTo-Json -Depth 10 | Set-Content "config.json"

Logging Function

Use this pattern for consistent logging:

function Log-Operation {
    param(
        [ValidateSet("SUCCESS", "ERROR", "INFO", "PENDING", "WARNING")]
        [string]$Status,
        [string]$Operation,
        [string]$Details,
        [string]$LogFile = "${env:DEVICE_LOGS}"
    )

    $timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
    $deviceName = $env:COMPUTERNAME
    $logEntry = "$timestamp - [$deviceName] $Status: $Operation - $Details"

    # Write to log file
    if ($LogFile -and (Test-Path (Split-Path $LogFile))) {
        Add-Content $LogFile -Value $logEntry
    }

    # Also output to console with color
    $color = switch ($Status) {
        "SUCCESS" { "Green" }
        "ERROR" { "Red" }
        "WARNING" { "Yellow" }
        "PENDING" { "Cyan" }
        default { "White" }
    }
    Write-Host $logEntry -ForegroundColor $color
}

# Usage
Log-Operation -Status "SUCCESS" -Operation "Install" -Details "Installed git via winget"
Log-Operation -Status "ERROR" -Operation "PATH" -Details "npm not found in PATH"

Known Issues Prevention

This skill prevents 15 documented issues:

Issue #1: Using bash commands in PowerShell

Error: cat : The term 'cat' is not recognized Why It Happens: PowerShell uses different cmdlets than bash Prevention: Use translation table above (cat -> Get-Content)

Issue #2: PATH not persisting

Error: Commands work in one session but not another Why It Happens: Setting $env:PATH only affects current session Prevention: Use [Environment]::SetEnvironmentVariable() for persistence

Issue #3: JSON depth truncation

Error: JSON output shows @{...} instead of nested values Why It Happens: Default -Depth is 2 Prevention: Always use ConvertTo-Json -Depth 10

Issue #4: Profile not loading

Error: Profile functions/aliases not available Why It Happens: Wrong profile location or -NoProfile flag Prevention: Verify $PROFILE path and check startup flags

Issue #5: Script execution blocked

Error: script.ps1 cannot be loaded because running scripts is disabled Why It Happens: Execution policy is Restricted Prevention: Set RemoteSigned for current user

Issue #6: npm global commands not found

Error: npm : The term 'npm' is not recognized Why It Happens: npm path not in system PATH Prevention: Add %APPDATA%\npm to User PATH via registry

Issue #7: PowerShell 5.1 vs 7.x confusion

Error: Features not working, different behavior Why It Happens: Using powershell.exe (5.1) instead of pwsh.exe (7.x) Prevention: Always use pwsh command or verify with $PSVersionTable

Using Bundled Resources

Scripts (scripts/)

Verify-ShellEnvironment.ps1 - Comprehensive environment check

.\scripts\Verify-ShellEnvironment.ps1

Tests: PowerShell version, profile location, PATH configuration, tool availability

Templates (templates/)

profile-template.ps1 - Recommended PowerShell profile

Copy-Item templates/profile-template.ps1 $PROFILE

Troubleshooting

Problem: Command not found after installation

Solution:

  1. Check PATH: $env:PATH -split ';' | Select-String "expected-path"
  2. Refresh session: Start new PowerShell window
  3. Check registry PATH vs session PATH

Problem: Profile changes not taking effect

Solution:

  1. Verify profile path: $PROFILE
  2. Dot-source to reload: . $PROFILE
  3. Check for syntax errors: pwsh -NoProfile -Command ". '$PROFILE'"

Problem: JSON losing data on save

Solution: Always use -Depth 10 or higher with ConvertTo-Json

Problem: Scripts from internet won't run

Solution:

# Unblock single file
Unblock-File -Path script.ps1

# Or set execution policy
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Complete Setup Checklist

  • PowerShell 7.x installed (pwsh --version)
  • Execution policy set to RemoteSigned
  • npm path in User PATH (registry)
  • Profile created and loading
  • .env file created from template
  • Verification script passes
