How to Run a Linux Command and Redirect its output to a socket in C
I have a Linux socket server program. I need to run the commands sent by the client and return the output to client. Is there a quicker way?
I tried with
ptr=popen(command, "r"); and then
fgets(buf, size,ptr);
write buf to socket
fgets hangs for me.
Now, I would like to know if I can re-direct the output of popen() or system() to the client socket. How can I do that?
Thank you very much.
