output file display -- Need Help

Hi everyone,

It has been a whlie since I wrote a program, and shamfully I didn't really learn C that well, but I do have background in several programming languages. So now I ran into a problem when coding an assignment.

Problem: My program needs to send unix command from client to server, and on server side, it will execute and output the command into a file and display the file on the client's screen.

Attempt:

Code:

---


system(cat temp);

---

where temp is the file that contain the executed unix command.

It will output the file to the screen, but it only displays the previous executed one. For example, if there are nothing in the file at begining, then if I type "ls", it will display nothing, but if I type "pwd", then it will displays the output of "ls".What do I need to do in order to display right? Thanks in advance.

Code:

---

system("cat temp");

---

That might help.

Thanks, but I did have the " ", just forgot to input it here.

BTW, a friend of mine said the file might need to close, but I don't see why I need to close it if I didn't call it in the code.
