Pattern Match

I am trying to create a script that will detect pattern matches. I subbed some things from an old script. But I must be forgetting something. This script is suppose to match the pattern in a SS number and display the message… “you got it correct” or Please try again. The info I am missing has to be something simple…I just don’t see it. Any help any one can provide would be appreciated. Thanks

$mynumbers = “[0-9]{3}-[0-9]{2}-[0-9]{4}”
$question1 =""

write-host “nnnnnn`n
“Press enter to Continue:””
while ($question1 -ne $mynumbers){
Write-Host “Do you know the format of your SS Number ?”
$question1 = Read-Host “Please enter your SS Number and Press the enter key”

if ($question1 -eq $mynumbers){
write-host " You know your formats"}
if ($question1 -ne $mynumbers){
write-host “Please try again”}

Sorry, the forums software doesn’t take kindly to back ticks. You might want to revise your code listing.

The problem is that you’re using the -ne operator, which means “not EXACTLY equal to” and -eq, which means “EXACTLY equal to.” You probably want to look at the -match and -notmatch operators instead, which work with regular expressions.

Hi Don,
I’ll give that a try and see what happens. I bet your right though.
Thank you for the help.

That should have been “you’re”. I hate it when I do that. I still had to change a few things other than match and not match…but it works.
Thanks again

You may want to use the digits class rather than explicitly defining a range.

$pattern = [regex]"\d{3}-?\d{2}-?\d{4}"
$input = Read-Host "Enter your SSAN"
$input -match $pattern

The question mark in the regex allows you to omit the dash. If you require the dash, remove the question marks.
