AutoIt help -> Using AutoIt -> Command Line Parameters:

The special array $CmdLine is initialized with the command line parameters passed in to your AutoIt script. Note the scriptname is not classed as a parameter; get this information with @ScriptName instead. A parameter that contains spaces must be surrounded by "double quotes". Compiled scripts accept command line parameters in the same way.

$CmdLine[0] is number of parameters

$CmdLine[1] is param 1 (after the script name)

$CmdLine[2] is param 2 etc


$CmdLine[$CmdLine[0]] is one way to get the last parameter...

So if your script is run like this:

AutoIt3.exe myscript.au3 param1 "this is another param"

$CmdLine[0] equals... 2

$CmdLine[1] equals... param1

$CmdLine[2] equals... this is another param

@ScriptName equals... myscript.au3

In addition to $CmdLine there is a variable called $CmdLineRaw that contains the entire command line unsplit, so for the above example:

$CmdLineRaw equals... myscript.au3 param1 "this is another param"

If the script was compiled it would have been run like this:

myscript.exe param1 "this is another param"

$CmdLineRaw equals... param1 "this is another param"

Note that $CmdLineRaw just return the parameters.

Note : only 63 parameters can be return by $CmdLine[...], but $CmdLineRaw will always returns the entire command line.

AutoIt specific command Line Switches

Form1: AutoIt3.exe [/ErrorStdOut] [/AutoIt3ExecuteScript] file [params ...]

Execute an AutoIt3 Script File

/ErrorStdOut Allows to redirect fatal error to StdOut which can be captured by an application as Scite editor. This switch can be used with a compiled script.

To execute a standard AutoIt Script File 'myscript.au3', use the command:

'AutoIt3.exe myscript.au3'

Form2: Compiled.exe [/ErrorStdOut] [params ...]

Execute an compiled AutoIt3 Script File produced with Aut2Exe.

Form3: Compiled.exe [/ErrorStdOut] [/AutoIt3ExecuteScript file] [params ...]

Execute another script file from a compiled AutoIt3 Script File. Then you don't need to fileinstall another copy of AutoIT3.exe in your compiled file.

Form4: AutoIt3.exe [/ErrorStdOut] /AutoIt3ExecuteLine "command line"

Execute one line of code.

To execute a single line of code, use the command:

Run(@AutoItExe & ' /AutoIt3ExecuteLine "MsgBox(0, ''Hello World!'', ''Hi!'')"')

The tray icon will not be displayed when using /AutoIt3ExecuteLine

NOTE: Correct usage of single- and double- quotation marks is important, even double single.
