There are quite a few scenarios that I run into routinely where I need a random value. A unique file name or password, perhaps. PowerShell makes this incredibly easy. This is one of those features that are so useful it makes you wonder how you got along without it.

Examples

 

Get ten random characters:

Get-Random -Count 10 -InputObject (65..90) | %{ [char]$_ }

Get fifteen random computer accounts for XP Workstations:

Get-ADComputer -LDAPFilter "(operatingsystem=*XP*)" | Get-Random -Count 15

Get some random records from your DNS cache:

Get-DnsClientCache | Get-Random

 

And that’s really the beauty of it…it works with any kind of collection.
