Why can't I read from stdout of hashdeep.exe?

[tip]

Hi to all,

I was writing a little script and I realized that I can not read from stdout stream of hashdeep.exe. Does anyone have an idea why I can't?

The code I'm running is:

$File1Pid = Run($HashDeeplocation & ' -c md5 -e "C:\File.avi"',@ScriptDir,@SW_SHOW, $STDOUT_CHILD)

While ProcessExists($File1Pid)

    $HashDeepTextRead = "-> " & StdoutRead($File1Pid)
    ToolTip($HashDeepTextRead)
    Sleep(10)

WEnd


//P.S.:"-c" option is to determine which hash algorithm to use and "-e" option is to show progress info.

I ran the code without $stdout_child opt and I can say that it is working the way it suppose to. But when I try to read from standart out stream I get nothing.

Hashdeep.exe can be obtained from here Hashdeep/md5deep

Thanks everybody in advance.

Regards,

Run this from SciTE and see if you get anything written to console:

Local $iPID = Run($sHashDeeplocation & ' -h"', "", @SW_HIDE, 6) ; $STDERR_CHILD + $STDOUT_CHILD

Local $sLine, $sLineError

While 1
    $sLineError = StderrRead($iPID)
    If @error Then ExitLoop
    ConsoleWriteError($sLineError)
    Sleep(100)
WEnd

While 1
    $sLine = StdoutRead($iPID)
    If @error Then ExitLoop
    ConsoleWrite($sLine)
    Sleep(100)
WEnd

If not the check $sHashDeeplocation because that really should print something.

When hashdeep.exe had completed hash calculation and exit it gave me these lines:

Console:

When I run the code with out $STDOUT_CHILD opt, I can read "File.avi: 50MB of 1400MB done, 00:00:26 left" on the command line window(updated every second). But when I enable $STDOUT_CHILD, the output(everything from the start to the end) is given at the end of the process like it is one complete message. Do you have an idea?

Hi to all, again,

I found out something new. When I run this code directly from commandline

hashdeep -c md5 -e "C:\File.avi" > 1.txt

I still see these lines in the commandline window: "File.avi: 1310MB of 1400MB done, 00:00:00 left"

And when everything is finished output to 1.txt is like this:

%%%% HASHDEEP-1.0
%%%% size,md5,filename
## Invoked from: C:\Hashdeep
## C:\> hashdeep -c md5 -e C:\File.avi
## 
4694479189,7707f090cd8c601eb63f663cdbed7372,"C:\File.avi"

There is nothing about progress info in the 1.txt.

I think it is related to how hashdeep.exe is coded. But is there a way to read progress info lines too?

Thanks again in advance.
