EXAMPLE: How To Catch ConsoleWrite() output to a file or to CMD

Recommended Posts

Few times there was disscusion how to show/store ConsoleWrite() message from GUI based script.

This is my solution.

To check how this work you should:

  1. Download and compile to exe file this scirpt: TESTING.au3
    ConsoleWrite('Some text' & @CRLF)
  2. Download and compile to exe file this scirpt: ConsoleWrapper.au3
    ;~ https://www.autoitscript.com/forum/topic/183043-autoit-console-data-to-file
    
    #pragma compile(Console, true)
    
    #include <AutoItConstants.au3>
    #include <MsgBoxConstants.au3>
    #include <FileConstants.au3>
    
    If $CmdLine[0] = 0 Then Exit
    
    Example()
    
    Func Example()
        Local $sCommand = $CmdLine[1]
        If $CmdLine[0] > 1 Then
            For $iCMD_idx = 2 To $CmdLine[0]
                $sCommand &= ' ' & $CmdLine[$iCMD_idx]
            Next
        EndIf
        Local $iPID = Run(@ComSpec & " /c " & $sCommand, @SystemDir, Default, $RUN_CREATE_NEW_CONSOLE + $STDERR_CHILD + $STDOUT_CHILD)
        Local $sOutput = _
                @CRLF & @CRLF & _
                'THIS IS LOG FILE FOR:' & @CRLF & _
                $sCommand & @CRLF & _
                'LOG START TIME: ' & _LogGetDate() & @CRLF & _
                'RESULT:' & @CRLF & _
                '=====================================' & @CRLF & _
                ''
    
        Local $hFile = FileOpen('ConsoleWrite_' & StringRegExpReplace(_LogGetDate(),'\D','_') & '.log', $FO_OVERWRITE + $FO_UTF8_NOBOM)
    
        ConsoleWrite($sOutput)
        FileWrite($hFile, $sOutput)
    
        While 1
            $sOutput = StdoutRead($iPID)
            If @error Then ; Exit the loop if the process closes or StdoutRead returns an error.
                ExitLoop
            EndIf
            ConsoleWrite($sOutput)
            FileWrite($hFile, $sOutput)
        WEnd
    
        $sOutput = _
                '=====================================' & @CRLF & _
                'LOG END TIME: ' & _LogGetDate() & @CRLF & _
                ''
    
        ConsoleWrite($sOutput)
        FileWrite($hFile, $sOutput)
        FileClose($hFile)
    
    EndFunc   ;==>Example
    
    Func _LogGetDate()
        Return @YEAR & '/' & @MON & '/' & @MDAY & '  ' & @HOUR & ':' & @MIN & ':' & @SEC
    EndFunc   ;==>_LogGetDate
  3. Run CMD
  4. in your CMD window you should make a command: ConsoleWrapper.exe TESTING.exe
    REMARK: as a parameter for: ConsoleWrapper.exe     you should use File Full Path for TESTING.exe file

I test it like this:

z:\Test>ConsoleWrapper.exe z:\Test\TESTING.exe


THIS IS LOG FILE FOR:
z:\Test\TESTING.exe
LOG START TIME: 2016/06/12  00:32:11
RESULT:
=====================================
Some text
=====================================
LOG END TIME: 2016/06/12  00:32:11

z:\Test>

Enoy yourself for testing :)

I think this is a much easier and better way to capture ConsoleWrite output from a compiled GUI AutoIt Script :)

#include <Process.au3>

$sExe = @ScriptDir & '\GUI Script.exe'

$sLogFile = @ScriptDir & '\output.txt'

$sCommand = @ComSpec & ' /c "' & $sExe & '" > "' & $sLogFile & '"'

_RunDos($sCommand)

Hi @mLipok, I tried with dos command

pscp -r -scp rrt_runin root@192.168.10.20:/usr/local/factory/

but AutoIT can not capture the output if this command fails

The fail output is like

rrt_runin: No such file or directory

The output can be captured by SciTe if I set workingdir in Run command as @ScriptDir or "", but using StdouRead() can not capture above line

This is my source code

#include <Constants.au3>
#include <Debug.au3>
#include <Array.au3>

Local $cDisk = Run(@ComSpec & " /c pscp -r -scp rrt_runin root@192.168.10.20:/usr/local/factory/","", @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD)
Global $cData = ""
While 1
    $line = StdoutRead($cDisk)
    If @error Then ExitLoop
    $cData &= $line
WEnd
While 1
    $line = StderrRead($cDisk)
    If @error Then ExitLoop
    $cData = $cData & @CR & $line
WEnd

MsgBox(0, "", "" & $cData)

FYI, the pscp program is installed when I install PuTTY

Best regards,

Luke

Sorry, It's me again. I'm trying to make some upgrade to my program.

Instead of using pscp, I changed to use scp since pscp have trouble downloading some *.a files.

The script can not catch the password prompt.

This is the output of my program running with CUI:

image.png.b6b3bb6d6427c01dff74fdceabcc4fc4.png

Inputting the password into this window directly WORKS.

EDIT, I read this article about Windows Command-Line, but this is beyond my current understanding.

EDIT, I tried Run function with parameter  $RUN_CREATE_NEW_CONSOLE + $STDIN_CHILD + $STDERR_MERGED, when running the .exe, no prompt appear. The prompt only appears with $STDIN_CHILD + $STDERR_MERGED.

However, if running by pressing F5 in SciTE, below is full output captured

It lacks the password prompt. I think the prompt is from another process than scp.exe. So the StdoutRead can't read it.

I dug into the content of Windows Command-Line: Inside the Windows Console, I realized that capturing the output of cmd.exe is very hard to achieve, as quoted from the link

Quote

There are some problems here because Console does things a little differently from *NIX:

  • Console and Command-Line app communicate via IOCTL messages through the driver, not via text streams (as in *NIX)
  • Windows mandates that ConHost.exe is the Console app which is connected to Command-Line apps
  • Windows controls the creation of the communication “pipes” via which the Console and Command-Line app communicate

What if you wanted to create an alternate Console app for Windows?

How would you send keyboard/mouse/pen/etc. user actions to the Command-Line app if you couldn’t access the communications “pipes” connecting your new Console to the Command-Line app?

Alas, the story here is not a good one: There ARE some great 3rd party Consoles (and server apps) for Windows (e.g. ConEmu/Cmder, Console2/ConsoleZ, Hyper, Visual Studio Code, OpenSSH, etc.), but they have to jump through extraordinary hoops to act like a normal Console would.

For example, 3rd party Consoles have to launch a Command-Line app off-screen at, for example, (-32000,-32000). They then have to send keystrokes to the off-screen Console, and screen-scrape the off-screen Console’s text contents and re-draw them on their own UI! I know, crazy, right?! It’s a testament to the ingenuity and determination of the creators of these apps that they even work at all.

Update for the case of scp command:

  • The call sequence: cmd.exe (@Comspec) => scp.exe/connhost.exe (sorry I don't know scp or conhost is run fist) => ssh.exe
  • The prompt belongs to ssh.exe process

Hello,

I found a workaround!
As scp stands for Secure Copy, it needs ssh.exe for the secure (encryption) part and it runs as the sequence in the above post.
Instead of running sole scp.exe command, I change the sequence a little bit, now I run ssh first (using plink.exe), then call
scp command lile below

plink.exe -ssh -t luke@172.18.65.109 scp -o "StrictHostKeyChecking=no" -r luke@172.18.65.109:/Temp/Luke/PON_Link_down_20190517/TestSCP/ ./2019-08-09

by doing so, I can capture & interact with the login prompt.

Sorry, EDITED. The workaround FAILED because it executes SCP in the remote server, not the current machine.
