Running bat files using axlRunBatchDBProgram

archive

A while back, Frank gave us a hint that bat files could be run within axlRunBatchDBProgram. This works well (thanks Frank) and is a graceful alternative to system commands. However, I have problems with directing output to files within my batch files. ie. I might want to include this line in my batch file: dir *.* > c:\temp\files.txt The files.txt file is not created. Does anyone have a good workaround or know why this doesn't work? Cheers, Dave

  • Hi Dave,

    Not sure how you start your command, but you might want to try this.

    start cmd /seperate mybat.bat

    This will open a new DOS command prompt, which is idenpendent of the axlRunDBBatchProcess. Like opening a link in a new Window in IE.

    Just the bat file may not work. I think SKILL is launching your command as a new child process and I remember that DOS doesn't like this with bat files because it has to invoke the command prompt first.

    So the following might work too

    cmd.exe mybat.bat

    I am not sure what benefit you gain compared to using the system command in SKILL?

    If that doesn't work, you could write yourself a small wrapper in java. I think I have one somewhere.

    Andy ;-)

  • Thanks Andy, I'll check out your ideas. Mye batch file runs OK but the redirect doesn't create a file.
    Why I don't like system calls: The system command opens a DOS window, albeit briefly, on the workstation. With multiple calls, this can be quite distracting to the user. Cheers, Dave

  • HI.  Did anyone ever have a solution for this?  I too am trying to avoid the system command to avoid the pop-ups. Although I don't need to run a bat file.   An example is the following CVS command:

    command prompt:   cvs watched >cvslog     this works and redirects the output to the cvslog file

     

    skill:     system("cvs watched >cvslog")     this also works as expected, including the

    redirect, but you get the cmd popup briefly

     

    axlSkill:  axlRunBatchDBProgram("cvs" "cvs watched >cvslog")  The cvs command works but the redirect does not work.  The same thing will happen using a bat file.  Adding cmd.exe in the bat file doesn't help either.  (ie. cmd.exe cvs watched >cvslog )

     

    So are redirects just not possible with axlRunBatchDBProgram or am I missing something?

     

    Thanks for any info!!

  •  Hi, Dave, Grungy Remnant.

    I have similar problem (shell( "hg branch > ../hg.tmp").

    Are you found solution?

    Also question: what difference between system() and shell(), without regard for returning value?
