Is there a PowerShell equivalent of `paste` (i.e., horizontal file concatenation)?

Question

I want to horizontally concatenate a bunch of CSV files using PowerShell. (When considering possible "duplicate" questions", please not that "a bunch" is not "two".) What is the PowerShell equivalent of the Linux paste command?

Answer 1

A few months ago, I submitted a proposal for including a Join-Object cmdlet to the standard PowerShell equipment #14994.

Besides complexer joins based on a related property, the idea is to also be able to do a side-by-side join (by omiting the -On parameter).
Taken this Paste command in Linux as an example:

$State =
'Arunachal Pradesh',
'Assam',
'Andhra Pradesh',
'Bihar',
'Chhattisgrah'

$Capital =
'Itanagar',
'Dispur',
'Hyderabad',
'Patna',
'Raipur'

Installation

Install-Module -Name JoinModule

Creating a side-by-side array:

1..5 |Join $State |Join $Capital |% { "$_" }

1 Arunachal Pradesh Itanagar
2 Assam Dispur
3 Andhra Pradesh Hyderabad
4 Bihar Patna
5 Chhattisgrah Raipur

Creating a side-by-side object:

1..5 |Join $State |Join $Capital -Name Number, State, Capital

Number State             Capital
------ -----             -------
     1 Arunachal Pradesh Itanagar
     2 Assam             Dispur
     3 Andhra Pradesh    Hyderabad
     4 Bihar             Patna
     5 Chhattisgrah      Raipur

Concatenate ("Paste") two objects:

$List = $State |Join $Capital -Name State, Capital
$Id = ConvertFrom-Csv @'
Id
A
B
C
D
E
'@

$Id |Join $List

Id State             Capital
-- -----             -------
A  Arunachal Pradesh Itanagar
B  Assam             Dispur
C  Andhra Pradesh    Hyderabad
D  Bihar             Patna
E  Chhattisgrah      Raipur
