linux + top command

I run the top command on my linux machine

and I see that vim command take like 99.5% CPU

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                                                                                                     
 23320 gsachde   25   0 10720 3500 2860 R 99.5  0.2  30895:11 vim  

how to verify which script/program is it?
