you need to use the command lsof, then the argument will be the directory you want to kill.
#!/usr/bin/env bash                                                                                                                                 
lsof $(pwd) | \                                                           
    awk -F " " ' { print $2 } ' | \                                       
    while read process ; do                                               
       [[ ${process} == "PID" ]] && continue;
          
          
          
          
          echo ${process};                                                 
     done
