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.

puts $:.find {|dir| File.file? dir + “/oci8.rb”}

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.

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