What follows is mostly command examples to illustrate things. Additional notes will be added sparingly.

There is the PowershellISE.

Powershell is CaseInsensitive but commonly things are in TitleCase like e.g. `Get-SmbShare`
```powershell
Dir; ls; copy; cd; move; ren; mkdir; rmdir; del
type # cat contents of file
Dir | more
dir > file.txt

cd hkcu: # gets to HKEY_CURRENT_USER in registry
new-psdrive -name flibble -psprovider filesystem -root c:\users
new-psdrive -name hexvision -psprovider filesystem -root \\mymachine\myshare\subdir

net use # can use external programs as expected

$files = Get-ChildItem -Path C:\Windows -Filter "*.exe"
$files # will dump variable to terminal
$env:Path # environment variables

Get-ChildItem # ls
Set-Location # cd
Move-Item # mv
Rename-Item # mv
Remove-Item # rm
Copy-Item # cp
Get-Content # cat
New-Item # Mkdir
Get-ChildItem -recurse

Get-Service
Get-Process
Get-EventLog
New-Service
```

### Help
```powershell
Get-Help Get-ChildItem -Online
Get-Help New-SmbShare | More
Get-Help *Move*
Get-Help Get-EventLogd
```

### Pipelines
Powershell sends **objects** down pipelines whereas [bash](/aw/lang/bash) sends text/binary down pipelines. Both approaches have advantages and disadvantages.
```powershell
Get-Process | Export-CSV procs.csv
Compare-Object # diff
Get-Process | Export-CliXML

# diff
Get-Process | Export-CliXML reference.xml
Diff -reference (Import CliXML) -difference (Get-Process) -property Name

Dir | Out-File DirectoryList.txt

Dir # is the same as
Dir | Out-Default

Get-Service | ConvertTo-HTML
Get-Service | ConvertTo-HTML | Out-File services.html

Get-Process | Stop-Process # DON'T DO THIS
Get-Process -name Notepad | Stop-Process # Stop all notepads


```
