The tail -f command continues to print messages, and you have to stop the session with a Ctrl + C command. This allows administrators to view a log message as soon as a system creates it. The tail -f command prints the last 10 lines of a text or log file, and then waits for new additions to the file to print it in real time. It’s possible to monitor new additions to a text file using the follow operator or -f option. As most log files and plain-text files, the commands work equally well. These commands are particularly useful for system administration and scripting purposes. For example, the command “tail -n 15 example.txt” will print the last 15 lines of the text file. If needed, you can change the number of lines printed by using the -n argument. The head command prints the first 10 lines of a text file, while the tail command prints the last 10 lines of a text file. Most system administrators have used the “head” and “tail” commands on their Linux terminals.
