As a matter of style, you should separate out the part of your program
that does the actual work from the part that does the input/output.
Structure it more like

def get_pid_from_name(process_name)
   #...
end

def kill_process(pid, signal)
  #...
end

# main program starts here

print "enter process name"
pname = gets.chomp()
print "enter signal"
signal = gets.chomp()

pid = get_pid_from_name(pname)
kill_process(pid, signal)
