String
Is equal (case insensitive)	if ($VAR1 -eq $VAR2)
Is equal (case insensitive) *	if ($VAR1 -ieq $VAR2)
Is equal (case sensitive)	if ($VAR1 -ceq $VAR2)
Regular expression **	if ($VAR1 -match "RegExp")

• * By default all PowerShell all comparison operators are case-insensitive. Prefixing with i makes this explicit.
• ** Regular expression matches will be available in $matches[].
