Translate the pseudo-code below into a C program to act like a small shell that processes
single commands entered by the user. In particular, the program assembles the command and
execute it. The commands/programs location can be anywhere in $PATH and might have arguments.
E.g., if the input-line entered by the user is
ls -F
your program should assemble this command-lines and execute 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
