This script simulates a small part of the linux
tail command. It's a small utility that helps reading / writing round-robin text files.
To print the last 10 lines of a file :
tail -n 10 <filename>
To print the content as it's written :
tail -f <filename>
n = number of lines to print. Example : -n 10
f = monitor the file for changes and print them
If the file size is verry small and you write a lot of odata into it (more than the file size) verry fast, tail might not be able to fallow you.
You can find documentation for this module with the perldoc command.
