How can you check the last available entries in the system log?

Using the command to display the last available entries in the system log is a common task for system administrators who want to monitor system behavior or diagnose issues. The reason why utilizing the specific command to view the end of the log is effective is that system logs can grow in size rapidly, making it impractical to view the entire log file at once.

The choice to use the command designed for this purpose, which displays the most recent entries, is advantageous since it allows administrators to review the most relevant and recent events that have occurred in the system. This command reads from the end of the log file, providing a quick overview of the latest system activities, errors, or notifications that are crucial for timely assessments and troubleshooting.

On the other hand, commands that attempt to display the entire log or just the beginning of it wouldn't serve this specific need as effectively. For example, commands designed to show only the first few lines would not give insights into the most recent issues or events, while displaying the entire file could overwhelm the user with unnecessary information. The command that lists the relevant log entries by accessing the log file in reverse order is optimized for this purpose.
