$CmdLine

[magician13134]

Ok, I just saw this in a couple scripts... and it confuses me. Not to much is returned on a forum search, and it's not in the help file.

So, as far as I can figure, it returns parameters of program as executed by Windows...?

But:

How do I use it?

Why doesn't it have to be declared?

It seems more like one of those terms starting with '@' than '$'...

Anyone up to giving me a brief explanation?

$CmdLine[0] Returns number of params

$CmdLine[1] 1st param

$CmdLine[2] 2nd param

In a DOS prompt, when you type:

C:> myprogram.exe 5 2

The 5 and 2 are command line parameters of the program. When your AutoIt script is run, anything passed to it in that fashion will be automatically put into a predefined array $CmdLine, where $CmdLine[0] is the number of arguments that were passed, and $CmdLine[1]... are the actual parameters.

So, when running:

C:> myautoitprogram.exe hello test

$CmdLine[0] = 2

$CmdLine[1] = "hello"

$CmdLine[2] = "test"

As to why it's not a macro (@), my guess would be because it's an array. I don't think there are any array macros, so it was set as a variable. You can treat it as a ubiquitous macro though, it gets declared and set when the program starts.

If you need the entire command line, use $cmdlineRaw

Note that you will have to properly parse the arguments yourself....
