Please help me to write a program that accepts a command from the terminal displaying a shell like prompt to accept the command.If the command is logout, the program is terminated. For any other command, it forks a child process passing the command to the child, and then waits for the child to terminate. The child process executes the command using one of the execution function, and then exists. The parent should then print the exit status of the child after analyzing the exit status using available macros, and again waits for the next command to read in. Note that a command may consists of many words seaprated by blanks. If the command is not a 'logout',the first word denotes an execuable file and the remaining words are parameters to the program in the executable file.

Thanks

This definitely looks like homework to me.. Search google for "writing your own shell" and check out this link.
