Running a UNIX command from Windows - UNIX for Dummies Questions & Answers

robbiegregg · #1 (**permalink**) 03-20-2005

Hi

I need to run a UNIX command from Visual C++ Windows program.

I was thinking of the Windows program generating a dummy file on the UNIX drive. On the UNIX box I could have a simple FORTRAN porogram searching continually for this dummy file and executes the UNIX command when the file exists.

However, this procedure is hardly elegant and was hoping someone out there has a better way of doing it?

Furthermore, I need a way of telling the Windows program the UNIX command has finished. Again, I could use a similar approach but would prefer a more elegant way of doing this!

** EXTRA INFORMATION **
The PC I use accesses a UNIX server over the network via Exceed and has SAMBA installed so Windows can see the UNIX drives.
The Windows program has been made using Visual C++ 6
The UNIX box is running Solaris (v8 I think)

Thanks for reading this thread

i think you need to run a service on the unix computer running on some port and write a client on windows to connect to it. i think its a security problem if you allow client to issue any commands so you have to know what you want exactly from the server.

for example this service using gawk gives out time to clients that connect to port 8888 similar to daytime:

Code:

BEGIN {
  print strftime() |& "/inet/tcp/8888/0/0"
  close("/inet/tcp/8888/0/0")
}

example client (gawk)

Code:

BEGIN {
  "/inet/tcp/0/localhost/8888" |& getline
  print $0
  close("/inet/tcp/0/localhost/8888")
}

You could add an ssh api to your windows C++ codebase, and execute the commands that way.
