title: Selecting a part of a file and copying that into new file in Linux
body: <p>How can I copy a particular content of a file into a new file using Linux?</p>
  
  <p>For example I have file called test.log file and it contains some 1000 lines. From those 1000 lines I need to copy the lines between 200 - 700 lines.</p>
  
  <p>Is there any single line command in LINUX/UNIX?</p>
