PowerShell Conditional logic Negation
Example
You may want to negate a boolean value, i.e. enter an if statement when a condition is false rather than true. This can be done by using the -Not CmdLet
$test = "test" if (-Not $test -eq "test2"){ Write-Host "if condition not met" } You can also use !:
$test = "test" if (!($test -eq "test2")){ Write-Host "if condition not met" } there is also the -ne (not equal) operator:
$test = "test" if ($test -ne "test2"){ Write-Host "variable test is not equal to 'test2'" }
