Write a C program to execute multiple Unix commands in parallel. 

•       The number of Unix commands is not fixed. 

•       There is no communication among the Unix commands. 

•       The Unix commands are given as command line arguments. 

•       For simplicity, you can assume that each Unix command has exactly one argument except that the last one can have either no argument or one argument.

For example, 

miniminishell cat openfile.c ls –l ps

includes three Unix commands: cat with one argument openfile.c, ls with one argument –l, and ps with no argument. 

For each Unix command, use a separate process to execute it. You need to print out each process id.
