[twincling] Need script to split one excel file into multiple files

[sampath]

  Hello friends
  
  I'm working an environment, where every day I need to split an excel file 
which contains thousands of mobile numbers and send to all the employees. Every 
day I'm doing this manually for nearly 50 employees. So its painful and time 
consuming. Is there scripts to split automatically and forward those to all. 
I'm working on Linux machine(openSUSE 11), so please help me.
  
                                                                                
                                                                          
Thanks&Regards
