Hello,

I need to be able to dynamically locate the file oci8.rb from a sh
script...
Do you have any idea how to do this ?

Many Thanks,

R.

Hum... My question was not precise enough. I am looking for the location
of the particular oci8.rb file that my current ruby interpreter is
using. As it has to be done at each execution of my program, I would
like to avoid scanning the entire file system. My ruby interpreter is
able to locate it, I would like to be able to do the same either in ruby
or in sh script. Any idea ?

Thanks,

R.

The interpreter searches the file in directories defined in $LOAD_PATH.
You can do the same ...

location = $LOAD_PATH.find { |dirname| File.exists?(File.join(dirname, filename) }
