Hello Again:

I am trying to use ExecuteUnixShellCommand to launch a unix app. Here is the output:

•RunTests("PH", "TAMU", 0.3)
  Unix command: cd '/Users/joe/Documents/Current Work/Kairos/V&V/Pressure_Drop';mpiexec -n 6 /Users/joe/projects/pronghorn/pronghorn-opt -i test.i
  do shell script "cd '/Users/joe/Documents/Current Work/Kairos/V&V/Pressure_Drop';mpiexec -n 6 /Users/joe/projects/pronghorn/pronghorn-opt -i test.i"
  sh: mpiexec: command not found
You'll note that I had to use single quotes to get around the space and the & in the path name. If I just simply copy the unix command and paste it into a terminal window, all works great.  The directory is changed and the app runs.  But for some reason, when using do shell script, it doesn't recognize mpiexec as a command.

I am running Igor 8.02 on an Intel Mac with Big Sur 11.5.2.  Here is ExecuteUnixShellCommand with a debug print statement:

Function/S ExecuteUnixShellCommand(uCommand, printCommandInHistory, printResultInHistory)
    String uCommand                         // Unix command to execute
    Variable printCommandInHistory
    Variable printResultInHistory

   if (printCommandInHistory)
    printf "Unix command: %s\r", uCommand
    endif

   String cmd
   sprintf cmd, "do shell script \"%s\"", uCommand
   ExecuteScriptText/UNQ/Z cmd      // /UNQ removes quotes surrounding reply
   Print cmd
           
    if (printResultInHistory)
    Print S_value
    endif

   return S_value
End

Thanks for the help,

   Joe Kelly

Possibly the directory containing mpiexec is not in the PATH environment variable when Igor is running.

Execute this in Terminal:

echo $PATH

Then execute this in Igor:

Print GetEnvironmentVariable("PATH")

You can use this in Terminal to find the directory:

which mpiexec

and then use a full path in the ExecuteScriptText command.

If you cd into the directory you could also invoke an executable with "./mpiexec" without changing the PATH.
