Vista Tutorial - match question

How would i do a statement to make sure an IP does not match an IP in a .txt
file i have?

Exampe:
$noAlertFile = get-content "noalert.txt"
$ip = "172.16.98.100"
if ($ip -notmatch $noAlertFile) {process} else {otherwise "do not alert"}

The noalert.txt file contains a list of IPs, what is a good way to see if
the $IP does not exist in the $noAlertFile object?

Thanks,
Ripp

Hello Ripp,



You can test if $ip exists in the file with the contains parameter, it returns
true/false respectively (true if exists):

PS > $noAlertFile -contains $ip

You can also use -notcontains (returns true if doesn't exist).
