The tail command will print the last ten lines of a file. tail is often used with the option -f, which tells tail not to quit at the end of file and instead follow the file as it grows. Use ctrl-C to exit this command. This is very useful if you need to track a file - Webmonkey production editors often use this command to tail our error logs. This gives us insight into exactly what an error is while it's happening so we can fix it quickly.
