Anchors in mutli-line regular expressions with PowerShell -match

Question

With -match, how do you tell it you want a Multi-Line match? https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about\_regular\_expressions?view=powershell-7.2#anchors doesn't describe that. Instead, it just links to a general .NET discussion that assumes you're working directly with those types.

Answer 1

You can use the "inline" regex method:

$mult = "aaa`nbbb`nccc`naaa`n"  
  
$mult -match "(?m)^(aaa)$"  # TRUE -- two results in $matches  
$Matches  
"------------------"  
$mult -match "(?s)^(aaa)$"  #FALSE -- two results in $matches  
$matches
