Hello all,

I need to use weka in a command line. Installing packages from command line work fine following this documentation :
http://weka.wikispaces.com/How+do+I+...age+manager%3F

But when i am trying use the installed packge, using :
java weka.Run weka.classifiers.functions.LibLINEAR (for example)

i got this error : Error: Could not find or load main class weka.Run

I am using the Linux version weka-3-7-10/

can you help please ?

Thank you for your time
