Get all the files here: http://JeremyThompson.net/Rocks/Mathematica/MmaWord.zip .Net Mathematica Word Library You will need to use a Microsoft library to open word documents. In a language such as .Net it is very easy; just open Visual Studio, reference the Microsoft.Office.Interop.Word .Net DLL (for Words) and the C:\Program Files\Open XML ...

(Reposting my comment as an answer) The reason this is happening is that the Mathematica launcher script sets LD_LIBRARY_PATH so that libraries included in the layout will be found and used, and that setting is inherited by any external process started from the kernel. But, sometimes it may happen that the external executable is linked against a conflicting ...

Under most operating systems you can use the 2>&1 handle redirection operator(1),(2): Import["!foo 2>&1", "Text"] "'foo' is not recognized as an internal or external command, operable program or batch file."

The problem is that the stdin stream for each process is being left open and needs to be closed. To demonstrate the issue, we create a single process: $process = StartProcess[$SystemShell]; WriteLine[$process, "echo example line"]; KillProcess[$process]; The call to WriteLine implicitly creates a stream object. Even though the process has been killed, ...

On Windows this works: Run["taskkill /im chrome.exe /f"] Run["taskkill /im WolframPlayerPro.exe /f"]

There are many ways to do this on a Mac. For example to open Safari: << "!open -a Safari" To open Safari to a particular file or page: << "!open -a Safari http://mathematica.stackexchange.com/questions/69247/how-to-close-external-app-from-mathematica" Now to close Safari: << "!osascript -e 'tell application \"Safari\" to quit'"

For those who will encounter the same problem as mine (and OP's), I added this answer. Mathematica now(since 10.0.0) has a new built-in function called RunProcess which does exactly what OP asked (including the standard error).

We had a bug like this on v. 10: it specifically stopped running new processes after you created 100 of them. This was fixed in version 10.0.1. I recommend testing it there, as version 10.0.1 has a number of improvements with respect to StartProcess. I can't test your example in MacOS right now, so please let me know if this isn't working on v. 10.0.1. ...

You can ask MMA to run the traditional ps,grep,kill,killall "unix" shell commands (using for example the RunProcess and Runcommands). The following is more a "Unix" post than a Mathematica one, but ... : For Unix, OS X sytems To "check if some application is opened" :ps and grep For example to see if the Chrome browser is running : myExternalCommand = ...

I actually found 3 ways to execute your command with RunProcess (on Unix like systems) : Let's write your command as a string : mycommand = "mdfind -onlyin /some/folder my_string"; but it could be any other command like : mycommand = "ls -la"; Then these 3 inputs are equivalent : RunProcess[StringSplit@mycommand] RunProcess[{$SystemShell, "-c", ... 3 Update -- finally got version 10 StartProcess version: the fortran: program ptest real*8 x do while(.true.) read(*,*)x write(*,*)x**2*cos(x)+1.d0 enddo end this is a simple endless loop, reading from stdin and writing to stdout. now in mathemaitca: pr = StartProcess["ptest"]; f[x_?NumericQ] := (Write[pr, FortranForm[x]]; ... 1 It may be possible - as noted by @MarcoB its quite a convoluted way of doing things. I would just download R and RStudio and work from there. However if you are set on using IBrokers via the R api via RLink try this (disclaimer it crashed for me on 10.1) : Needs["RLink`"]; InstallR[]; REvaluate["install.packages(\"IBrokers\")"]; ... 1 To call an external command with input parameters like *argv[] in C (I don't know how is it called in Fortran) you can use this Mathematica routine: RunProcess[{$SystemShell, "-c", ExecutableFileName <> " " <> arg1 <> " " <> arg2 <> " " <> arg3}, "StandardOutput"] This will also give back output as a result of the ...
