Need simple example of Command Line Parameters

5 posts in this topic

Can someone point me to a 20- or 30-line script that uses Command Line Parameters? (I've searched several times.) I've read about them in the Help file, but I'm still unsure how to declare them -- or are they pre-declared in one of the constants files? An example would really help.

Thanks in advance.

Something like this ?

#include <date.au3>
#cs ----- CleanUp ------
    A command line executable that deletes files in a given folder
    that are over a given age. 3/23/06
    
    Example:
    C:\cleanup.exe "c:\test\*.*" 60 /R /D

here is something really simple..

$DAT = ''
If $CmdLine[0] > 0 Then
    If $CmdLine[1] <> @ScriptName Then
        $Dat = $CmdLine[1]
    
                Endif
Endif
;Do whatever you want with Dat down here...

Thanks for both responses. Here's a script I came up with to confirm/demonstrate parameter entry:

If $CmdLine[0] = 0 Then
    MsgBox(64, "Result", "No parameter was entered!")
    Exit
EndIf
MsgBox(64, "Entry", $CmdLine[1])

My conclusion is that the $CmdLine arrary is some type of global parameter that doesn't have to be declared. Are there others? I couldn't find anything specific in AutoIt Help.
