title: can command line utilities be faster than C++?
body: <p>I have a project where I want to manipulate certain output files.</p>
  
  <p>This can be accomplished using a combination of grep and sed and piping with |</p>
  
  <p>Alternatively, I can also write a C++ program to do the same thing.</p>
  
  <p>Is there a conclusive answer on which method will be faster since grep and sed should already be fairly well optimised?</p>
