They are provided 'as is' for your review and for your reuse.

There is a [blog post](https://blog.lksz.me/keeping-track-of-everything/#-mypsscriptroot) about how to clone this repo and use it as your own.

The scripts all [assume](https://blog.lksz.me/functions-or-scripts/#myprofilecode) the code below is part of one of your $PROFILE files.
The code establishes the following variables:
* `$PathEnvDelimiter` - Linux/Unix it's `:`, while in Windows it's `;`
* `$MyPSModulePath` - Location to place personal Modules
* `$MyPSScriptRoot` - Location of personal Scripts.
This envrionment can be installed using one the following options:
### The Short, yet safer way
```PowerShell
iwr https://lksz.me/pwsz | iex
```

The code also makes sure `$MyPSScriptRoot` is in the `$env:PATH` environment vairable, and finally it calls [`Reload-MyAliases`](https://blog.lksz.me/a-case-of-sensitivity/#myaliases) if it exists.
This sets up the `$PROFILE` file, and initilizes the default dir, but nothing else is done.
Cloning the repo, is something you'll need to deal with on your own, or you can call the next line.

### The [prefered] Short, but with control option
```PowerShell
$sfw=1; iwr https://lksz.me/pwsz | iex; _setup [-sudo] [-Force] [-GitClone] [-GitURL <alternative git URL>] [-WhatIf] [-Confirm] [<CommonParameters>]
```
$global:PathEnvDelimiter = $(if( $PSVersionTable.Platform -match 'unix' ) {':'} else {';'})
function Split-PathEnv {
param([string]$EnvPath)
$EnvPath -split $PathEnvDelimiter
}

$global:MyPSModulePath = Split-PathEnv $env:PSModulePath | Where-Object { $_ -match "^$(Resolve-Path ~)" }

if( -not $MyPSModulePath ) {
$MyPSModulePath = Resolve-Path ~/powershell/Modules
if( -not (Test-Path $MyPSModulePath) ) {
New-Item -ItemType Directory -Path $MyPSModulePath -Force | Out-Null
}
$env:PSModulePath = "$MyPSModulePath$PathEnvDelimiter$env:PSModulePath"
}

$local:p = Split-PathEnv $env:PATH
$global:MyPSScriptRoot = Join-Path (Split-Path -Parent $MyPSModulePath) Scripts
if( -not (Test-Path $MyPSScriptRoot) ) {
New-Item -ItemType Directory -Path $MyPSScriptRoot -Force | Out-Null
}

$p = @($p[0], $MyPSScriptRoot) + $($p | Select-Object -Skip 1)
$env:PATH = $p -join $PathEnvDelimiter

Get-Command Reload-MyScripts -ErrorAction SilentlyContinue | ForEach-Object { . $_.Name }
```

This will setup the `$PROFILE` file properly, and when the `-GitClone` switch is used, the git repo is cloned into `$MyPSScriptRoot`.

### The 'I don't trust one liners, what's going on ?!?' option
Follow the instructions in the initial [blog post](https://blog.lksz.me/keeping-track-of-everything/#-mypsscriptroot) which contains the steps for cloning and using the env as your own.

In the above one-liners, `https://lksz.me/pwsz` actually points to the [Setup-Profile.ps1] file, which means, that after you have the `Scripts` directory setup, you can all `Setup-Profile` to setup the `$PROFILE` file.
