Title: Try different tail options that were not demonstrated

Time: 5-10 minutes

Purpose: Try different settings for viewing a file to get information in a more relevant way.

Introduction:
In the demos we saw how the tail command would return the last 10 lines of a file by default. We also tried using tail to automatically watch for updates to a file. This update happens about once a second. So what if viewing just the last 10 lines of the file was too much or too little? What if you didn’t need to get an updated view of a file every second? (Refreshing files that have big updates too often can have a performance impact on your machine or the server.)

Activity:

  1. Try to get tail to return a specific number of lines that you require.
  2. Get tail to only update once every 5 seconds when using the -fargument.
