Question

Create a shell program called "myprog" that prints "Hello" (use echo). 
Remember it must
start with "Shebang" and the entire path to a bash shell. So you need at least 2 lines of codes, though
use a blank line between the two. Give the program rights so you have all the rights,
your group reading and driving rights, and everyone else just driving rights.
Now run your shell program. How can you run the program? Why is just the name for
command not enough? (Tip: check $ PATH - you need two characters before the command).
Specify:
1. the contents of your shell program
2. the command to set the permissions (test with other users if necessary)
3. a long list showing the rights to the program
4. command to run the program
arguments

Instead of the text "Hello", the first argument of the shell program should now appear. Then you have to
again use a special shell variable.
5. What do you need to use in your program to use the first argument? (2 characters)
