The simplest method is to invoke the system() library function.
If your program needs to provide input to, or capture output from,
the command, then popen() should be used.
If you need to do something more elaborate then you need to study
UNIX system programming; Kernighan & Pike's "The UNIX Programming
Environment" is recommended.
