Problem: How to make an customized System command

I want to make a system command, which is special.
That means, for example that you can move files. MV ( I'm talking from Linux) is always the same, but not the file and the target folder. And how I can bring this in the system command?
Because the files can change and so on...

I think you're asking for something like this:

Code:

---

char filename[100] = "a_file";
char dirname[100] = "a_directory";
char cmd[250];

sprintf(cmd, "mv %s %s", filename, dirname);
system(cmd);
