StdOutRead(): is it possible to "Attach" to a lauched CMD.EXE?

[rudi]

Hi.

I'm just wondering, if it might be possible, to open a CMDline Program and to use StdOutRead() / StdErrRead() to "tee" the output to one log file? I want to still be able to interact with the CMDline Program (type in commands, read the StdOut StdErr Output).

Is "tee-ing" possible with StdOutRead() / StdErrRead()

expandcollapse popup

#include <date.au3>
#include <Constants.au3>

;  0x2 ($STDOUT_CHILD) = Provide a handle to the child's STDOUT stream
;  0x4 ($STDERR_CHILD) = Provide a handle to the child's STDERR stream

$Log = "C:\temp\Std-out-err-read.txt"
$hLog = FileOpen($Log, 2 + 8)
FileWriteLine($hLog, _NowCalc())
FileWriteLine($hLog, "--------------------------------------------------------------------------------------------")

$ExitReason = ""

; when I specify $stdout_child / $stdout_child + $stderr_child, the process dies immediately.
; When I truncate the line, so that it ends " ...,@sw_show)", the cmd box remains open as expected.
$pid = Run(@ComSpec & " /k echo this is a first line...", @TempDir, @SW_SHOW, $STDOUT_CHILD + $STDERR_CHILD)
While ProcessExists($pid)

    $StdOut = StdoutRead($pid)
    If @error Then
        $ExitReason &= "StdOutRead Error " & @error & @CRLF
        ExitLoop
    EndIf
    If $StdOut <> "" Then FileWrite($hLog, $StdOut)

    $StdErr = StderrRead($pid)
    If @error Then
        $ExitReason &= "StdErrRead Error " & @error & @CRLF
        ExitLoop
    EndIf
    If $StdErr <> "" Then FileWriteLine($hLog, $StdErr)

WEnd

FileWriteLine($hLog, @CRLF & "--------------------------------------------------------------------------------------------")
FileWriteLine($hLog,_NowCalc())

ConsoleWrite($ExitReason & @LF)
FileWriteLine($hLog,$ExitReason)
FileClose($hLog)

Run ("notepad.exe " & $Log)

the CMD box just "blinks" once and disappears. Output to file is this:

2013/02/05 13:54:16
--------------------------------------------------------------------------------------------
this is a first line...

C:\Users\admin\AppData\Local\Temp>
--------------------------------------------------------------------------------------------
2013/02/05 13:54:16

Propably simply WAD?

What's wrong with what you have now?

Hi.

"cmd.exe /k echo something" should *NOT* close, after the command was executed. But the CMD box opens, and instantly closes again. So I cannot type further commands into that box. When you alter the script above, so that the *_child values are *NOT* specified, the box remains open, as needed. But then, obviously, the printable output is not logged to file.

So...

• StdIn shall remain connected to the keyboard
• StdOut + StdErr shall display to the box *AND* at the same time be logged to file.

Finally I want to use this for the IBM TSM Backup Server Command Line Tools ("dsmadmc.exe" / "dsmadmc.exe -console") to log all visible output to a text file, to be able to get all commands typed into the box and all system responses for documentation purposes.

Basically like that "PUTTY.EXE" option "log all printable output to file".

Any other approach to achive this would be fine.

Replace

$STDOUT_CHILD + $STDERR_CHILD

with

BitAnd($STDOUT_CHILD, $STDERR_CHILD)

Here it works now.
