So, I guess the questions are:1. Do you have a /usr/bin/ruby1.8 and is it a binary file (about 3336 bytes)?2. Does /etc/alternatives/ruby1.8 exist and what type of file is it? 3. Where is your wrapper script ruby1.8 located?4. And, if both the wrapper ruby1.8 and /usr/bin/ruby1.8 exist, in different places, and your wrapper is executable, which of the two is being found in the PATH search?
So, my questions got answered, even as I was sending them. What you have, then, is this:
$ matz.rb
generates:
/usr/bin/ruby1.8 /path/to/script/matz.rb # wrapper
generates
/bin/sh /usr/bin/ruby1.8
does:
export variable
exec /etc/alternatives/ruby1.8 /usr/bin/ruby1.8
The only place the original file gets mentioned is at the very
beginning, it does not pass through to the real ruby1.8 command.
So, what does ruby do when it sees a file with "#!/bin/sh" at the beginning, let alone the 'exec' line?
I really can't say what exactly is letting things get back to the 'puts' in the original script file, what I can say is this setup looks to me like it won't work. Of course, this assumes my analysis is correct.
I'll be mulling this over, I'm sure, I can't let a good problem like this rest ;) So, hopefully sooner than later, it will get solved.
