Hi Todd!=

!#/usr/bin/env ruby

it needs the token (i.e. program e= xecutable name) in front of the env token. This makes your script portable.=

You will want to make it exectutable which is done with the comma= nd chmod like so:

% chmod +x /path/to/your-program

from there to exectute it you can do it one of three ways.

1. simply use dot slash in front of the program like: ./prog

2. ty= pe the whole path like: /home/todd/prog

3. set up a bin directory = and set up your the PATH variable in your shells rc file.

The last one is your homework =3D) With that you can just run your script=20 from anywhere and even incorporate it into other scripts and so on.

Congratulations and welcome to the wonderful world of UNIX and Ruby P= rogramming =3D)

Oh and one last word of advice. AUTOMATE EVER= YTHING!

When I try to kick off a simple script

#!/usr/bin/env

puts "Hello"

I get

./test.rb: line 1: #!/usr/bin/env: No such file or directory
./test.rb: line 4: puts: command not found

Why?

Thanks
