This script simulates a small part of the linux tail command. It's a small utility that helps reading / writing round-robin text files.
tail
To print the last 10 lines of a file :
tail -n 10 <filename>
To print the content as it's written :
tail -f <filename>
Parameters :
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.
