====== Interactive Mode ======
===== History =====
  * Use ''h'' or ''history'' command to list history
      * Use ''#<num> <tab>'' to recall the command to the command prompt without executing it
      * Use ''Invoke-History <num>'' or ''r <num>'' to execute the specified command
      * Open stored history in text editor.
          * ''notepad (Get-PSReadlineOption).HistorySavePath''

  * Use ''get-history | out-gridview -Passthru | invoke-history'' to get and invoke command from history using a grid view. Alternatively, ''h | ogv -p | r''. Or, just create a function for it, ''function hh {get-history | out-gridview -Passthru | invoke-history}''
  * Use ''Ctrl+r'' to interactively search backward through history and ''Ctrl+s'' to search forrward
======Operators======
  * [[https://msdn.microsoft.com/en-us/powershell/reference/5.1/microsoft.powershell.core/about/about_comparison_operators|Comparison Operators]]

======Variables======
  * ''Get-Variable'', to list all variables in the current session
==== Basic Scalar Example ====
<code powershell>
$fname = "Spunky"
$lname = "Violet"

Write-Host "World meet $fname $lname."
</code>

=====Built-in/Automatic/Special Variables=====
  * ''$?'', exit code of last operation
  * ''$ARGS'', array of arguments passed to script.
  * ''$NULL'', variable that represents //null// value, big surprise.
  * ''$true'' and ''$false'' represent the boolean values
  * ''env:'', pseudo drive for environment variables

====== Input/Output ======

Example of using Out-GridView for handy way to get output
<code powershell>
Get-Alias | Out-GridView
</code>

Example of selecting a property from objects
<code powershell>
$files = ls .\* -Exclude @("*.tmp")

$files | select -Property FullName 

# Alternative: this method does not include the property header that is included with the Select-Object method above
$files | foreach {$_.FullName}
</code>
======Conditionals======

=====If Statement=====

<code powershell>

if (Test-Path $file -eq $True)
{
    Write-Host "Found a file."
}
else
{
    Write-Host "No file found."
}

</code>

<code powershell>
if ($a -gt 2)
{
    Write-Host "The value $a is greater than 2."
}
elseif ($a -eq 2)
{
    Write-Host "The value $a is equal to 2."
}
else
{
    Write-Host "The value $a is less than 2 or was not created
or initialized."
}
</code>
======Miscellanea======

===Allow all scripts to be ran===
<code powershell>
Set-ExecutionPolicy bypass
</code>

===One-liner===
  * ''-executionpolicy bypass'', overrrides local system policy configuration to allow any script to run. Sometimes you just need to get things done.

<code powershell>
powershell -executionpolicy bypass -command <command text>
</code>
