QUESTION

Powershell: generate unique semi random numeric strings

Asked 2020-Jun-25 at 20:06

Requirement: generate 10k of unique numbers composed of a sequential number (16 digits) followed by a random numeric string (4 digits). Weapon of choice is Powershell because it's the only tool I have a very limited knowledge of.

Problems encountered:

Generating 10k sequential numbers using the following method: 1400000000000000..1400000000010000 and putting into a variable. Error: Value is to large for an Int32
Generating 10k of 4 digit via Get-Random -Minimum 0001 -Maximum 9999 and putting them in a variable. I manage only to obtain 1 random number.
Combining the two variables using the Join-Object (or at least that's what I hope could be done)

How can I combine these 3 commands to obtain a list of semi random numbers as specified above? Or is there simpler way to achieve the same result?

The classic algorithm for creating an unique sequence is to put all the values into an array. Pick a value. Move the last value of the array into the place from where you just picked the value. Then decrease the array's size by one. This creates a copy of the array, so if there are lots of values, be wary of the extra cost that is caused by resizing an array.

An example that shuffles values from 0 to 19 is like so,

This Join-Object is based on script rather than a module, this means that you might first "install" (download) it on another machine and that just copy/paste it (or the contents) to your server. You might also download it from the project site and dot-source the script: . .\Join-Object.ps1.

Specific to your question:
As @Theo commented "Duplicate column names is a bad thing in csv", especially in PowerShell where a ConvertFrom-Csv cmdlet will cause an error on such a csv file.
The Join-Object script has although a possibility to join object based on the row index by simply omitting the -On parameter. In that case it will put columns that exist on both sides in an array by default:
