What are other uses for tail?

The tail command has several useful applications beyond just monitoring log files. Here are some common uses:

1. View Last N Lines:

   tail -n 10 filename.txt

   This displays the last 10 lines of filename.txt.

2. Monitor Log Files in Real-Time:

   tail -f /var/log/syslog

   This continuously displays new entries added to the system log.

3. Skip the First N Lines:

   tail -n +5 filename.txt

   This shows the content of filename.txt starting from the 5th line.

4. Combine with Other Commands:

   cat filename.txt | tail -n 5

   This displays the last 5 lines of the output from cat filename.txt.

5. Use with Pipes:

   dmesg | tail -n 20

   This shows the last 20 lines of the kernel ring buffer messages.
