title: How to determine if a specific module is loaded in linux kernel
body: <p>I am just curious is there any way to determine if a particular module is loaded/installed. </p>
  
  <p>$lsmod lists all modules (device driver loaded).</p>
  
  <p>Is there any way to check or a command that returns true/false boolean output if a module name is polled. for eg. if keyboard.o exists return true else false. i need this tip to complete my driver auto refresh program.</p>
  
  <p>PS: tried modinfo. i am using busybox client in my test DUT so can you give some alternatives other than modinfo ?</p>
