Viewing The Log File
Part of the Fundamentals section of Coddy's Terminal journey — lesson 49 of 82.
Challenge
EasyNow that you've seen the full log file, let's practice viewing specific portions of it. When analyzing large log files, you often want to see just the beginning or end rather than the entire file.
Use head to display only the first 5 lines of server.log.
head -n 5 server.logTip: The
headcommand is useful for quickly previewing the structure of a log file. In the next lesson, you'll start filtering this log to find specific types of entries.
