Todd to know more about chmod read the man page:

% man chmod=

It stands for change mode. Basically it's turning on the exec= ute bit when you use +x.

Hi Todd!

!#/usr/bin/env rub= y

it needs the token (i.e. program executable 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.

When I do which ruby, I get /usr/bin/ruby
When I do ruby -v I get ruby 1.9.3p0 (2011-10-30 revision 33570)
[i686-linux]

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

Todd
