Generate random numbers in PowerShell with Get-Random

Have you ever wanted to generate random numbers for passwords, test data…. and wondered how you could easily generate them?

Well I was confronted by the same situation on one of our servers where I needed some random numbers for inputting wait times to test an application but didn’t have my usual tool of choice ( MS Excel ) available to me.

I remembered the Get-Random command from memory but used the Get-Help command to allow me to use the correct syntax.

Executing Get-Random will produce a random number.

get-random
get-random

 

This was quite a good start but then I needed only 4 digit figures and I then had to use the minimum and maximum parameters.

Get-Random -Maximum 9999 -Minimum 1000

The above command solved that problem for me and I think it reflects how easily readable the PowerShell language is.

The last scenario I had was producing random numbers for some temporary passwords. I looked at the help for Get-Command and noticed the inputobject and count parameters which I thought would fulfil my need.

Get-Random -InputObject (10000..99999) -Count 3

The above command shows the range of values which I gave and the number of random numbers I needed in the Count parameter.

Hopefully the above will help you with your random number needs. Please add your feedback or other solutions in the comments below.
