How to Source all powershell scripts from a directory

Question

Can not dot source all PowerShell scripts from directory tried:

. .\*.ps1

Returns this:

> function, script file, or operable program. Check the spelling of the

Answer 1

Use Get-ChildItem to grab all *.ps1 files, then loop through them with ForEach-Object and dot-source them individually

$Path = "C:\Scripts\Directory"
Get-ChildItem -Path $Path -Filter *.ps1 |ForEach-Object {
    . $_.FullName
}

If you put the above in a script, and the script itself is located in $Path, make sure to exclude the file itself so as to avoid it recursively dot-sourcing itself over and over again:

$Path = "C:\Scripts\Directory"
Get-ChildItem -Path $Path -Filter *.ps1 |Where-Object { $_.FullName -ne $PSCommandPath } |ForEach-Object {
    . $_.FullName
}

Used the above to define a folder called Functions under my executing script. Works just fine in PS5:

## Folder\myIncluder.ps1
## Folder\Functions\Some-Function.ps1          -included
## Folder\Functions\Some-Other-Function.ps1    -included
## Folder\Functions\Some-Other-Function.readme -not included
(Get-ChildItem -Path (Join-Path $PSScriptRoot Functions) -Filter *.ps1 -Recurse) | % {
    . $_.FullName
}

Figure this makes it easy for the next lazy person to just adopt the same structure :p

Answer 2

This should work:

Get-ChildItem -Filter '*.ps1' | Foreach { . $_.FullName }
