title: Trigger shell script if a file has been modified
body: <p>I have created a shell script which basically does 2 function,</p>
  
  <p>1.Loads the data from .csv into table using sql loader.</p>
  
  <p>2.Runs a procedure in oracle DB once the data is loaded.</p>
  
  <p>What i want to know is that if someone populates the .csv file with valid data,i want to trigger the shell script automatically after waiting for 1 minute</p>
