Translated the pseudo-code below into a C program to act like a small shell that process single command entered by the user. In particular, the program assembles the command and executed. it. The command/programs location can be anywhere in $PATH and might have arguments.

E.g., if the input-line entered by use is

Is-F

your program should assemble this command-lines and executed it.

The Pseudo-code

Algorithm: While (1) begin read command line from user // Use Unix read/write system calls assemble command args. duplicate current process (fork) child should exec to the new program parent process waits for its child to terminate end
