hard📝 Application Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Understand platform conditions
You want to create the folder only on Windows or macOS, so the condition should check if either $IsWindows or $IsMacOS is true.Step 2: Analyze each option
if ($IsWindows -or $IsMacOS) { New-Item -ItemType Directory -Path './Logs' } uses -or to combine $IsWindows and $IsMacOS correctly. if ($IsLinux) { New-Item -ItemType Directory -Path './Logs' } creates folder only on Linux (wrong). if ($IsWindows -and $IsMacOS) { New-Item -ItemType Directory -Path './Logs' } uses -and which requires both true (impossible). if ($IsUnix) { New-Item -ItemType Directory -Path './Logs' } uses undefined $IsUnix which is falsey (wrong).Final Answer:
if ($IsWindows -or $IsMacOS) { New-Item -ItemType Directory -Path './Logs' } -> Option AQuick Check:
Use -or for Windows or Mac condition [OK]
Quick Trick: Use -or to combine platform checks for multiple OS [OK]
Common Mistakes:
- Using -and instead of -or for multiple platforms
- Creating folder on Linux by mistake
- Using undefined variables like $IsUnix
