Part II

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.
