PowerShell Windows — Scripting Rules
Essential rules for correct PowerShell usage on Windows. Follow these rules to avoid common errors when executing shell commands.
Core Principles
1. Command Separation
- Wrong:
cd "path" && command(bash syntax) - Correct:
cd "path"; command(PowerShell syntax)
2. Path Quoting
- Always use double quotes for paths with spaces:
cd "D:\My Projects\MyApp"
3. Script Execution
- For .bat/.cmd files:
./gradlew clean build
.\gradlew.bat clean build
4. Docker Commands
- Specify full path to docker-compose files:
docker-compose -f "D:\My Projects\app\docker-compose.yml" up -d
5. HTTP Requests
- Wrong:
curl -s http://localhost:9090/status - Correct:
Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
6. Waiting/Delays
- Wrong:
timeout 10 - Correct:
Start-Sleep -Seconds 10
7. JSON Handling
- JSON parsing:
$response = Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
$json = $response.Content | ConvertFrom-Json
$json | ConvertTo-Json -Depth 3
8. Process Checking
- Process search:
Get-Process -Name "java" -ErrorAction SilentlyContinue
9. Docker Operations
- Stop containers:
docker-compose -f "path\to\file.yml" down
- Build images:
docker-compose -f "path\to\file.yml" build --no-cache
10. Error Handling
- Ignore errors:
Get-Process -Name "java" -ErrorAction SilentlyContinue
Common Errors and Fixes
| Error | Cause | Fix |
|---|---|---|
&& is not recognized |
Using bash syntax | Replace && with ; |
curl not found |
curl not installed on Windows | Use Invoke-WebRequest |
timeout not found |
timeout not supported | Use Start-Sleep |
Path not found |
Missing quotes on spaced path | Wrap path in double quotes |
Correct Command Examples
# Change directory and execute command
cd "D:\My Projects\MyApp"; ./gradlew clean build -x test
# Wait and make HTTP request
Start-Sleep -Seconds 10; Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
# Docker operations
docker-compose -f "D:\My Projects\MyApp\docker-compose.yml" down
docker-compose -f "D:\My Projects\MyApp\docker-compose.yml" build --no-cache
docker-compose -f "D:\My Projects\MyApp\docker-compose.yml" up -d
# Check server status
$response = Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
$json = $response.Content | ConvertFrom-Json
Write-Host "Transport: $($json.mcp.transport)"
These rules are critically important for proper operation in Windows PowerShell environment.
