Write a program that takes a list of command line arguments, each of which is a full path of a command (such as /bin/ls, /bin/ps, /bin/date, /usr/bin/who, /bin/unameetc). Assume the number of such commands is N, your program would then create N child processes, each of which executing one of the N commands. You should make sure that these N commands are executed concurrently, not sequentially one after the other. The parent process should be waiting for each child process to terminate. When a child process terminates, the parent process should print one line on the standard output stating that the relevant command has completed successfully or not successfully (such as"Command /bin/who has completed successfully"). Once all of its child processes have terminated, the parent process should print "All done, bye-bye!" before it itself terminates.
