shebang! on Leopard

[Paul M.]

Hey everyone,

having a little trouble with shebang! on a iMac running Leopard.

been looking at the other posts and none of the solutions seem to be
working.

I'm new to Ruby, and would really like to figure this out before I move
on with my book.

So I'm trying to get this script to run:

puts "Hello, Matz!"

I ran "which ruby" from the terminal and the path says: /usr/bin/ruby

so I edited the script to:
#!/usr/bin/ruby
puts "Hello, Matz!"

and I get the following error: -bash: matz.rb: command not found

So what am I missing here?

Thanks

Does your script file have Unix line endings? m.

Your script is not in $PATH ?
try ./matz.rb

If you mean: pauls-imac:~ paulsimac$

Then the answer is yes.

my apologies, if I misunderstood your question.

Tried that, and I get: -bash: ./matz.rb: No such file or directory

? What does
ls -l matz.rb
show?

 

[Paul M.]

? What does
ls -l matz.rb
show?

it shows: -rwxr-xr-x@ 1 paulmaxfield staff 35 16 Jun 09:26 matz.rb

Wow. And in that same directory,
/matz.rb
gives you a no such file or directory message?? Strange.

Try this:
od -a matz.rb

and post the result.

Could you describe *exactly* what you are doing? How are you creating
and saving the script, and then what are you doing in order to run it?

m.

m.

And have you tried each command suggested in the SAME terminal window?
Each terminal window (or rather the bash shell it invokes) have its
own current work directory.

You might want to make sure that /usr/bin/ruby is actually there.
It might be a broken link or gimped binary. Try this test:

/usr/bin/ruby ./matz.rb

(make sure you're rooted in the same directory as the matz.rb script
or give the full path to matz.rb). As far as I know, Leopard ships
with ruby 1.8.6 patch 87 (?), so it should be there and functioning...
This is a pretty strange problem.

 

[Louis-Philippe]

or type:which ruby
in your bash shell... then report the results

Problem fixed. My mistake, when I tried the ./ I was in the wrong
directory, script is working now. Thanks everyone who took time to reply
to this post, much appreciated.
