You call sleep only when the file is updated. As long as the file is not

while True:
new_time = o
When running the program cpu usage is 100%. Here is the part that is
running;

new_time = os.stat(fname).st_mtime
if new_time > old_time:

Alan, thanks for your time and great tips :)
You're welcome, I was in a hurry so wasn't sure I understood fully.
Here is what I came up with;
def print_log_end(fname, bufsize, linesep):
f = open(fname, 'r')
f.seek(-bufsize, os.SEEK_END)# goto one buffsize away fro

I got confused trying to work out exactly what this was doing.
pos is initially the number of times b

Some general comments first:
def tail_it(bufsize=8192, linesep=__import__('os').linesep):
No idea why you are using the import stuff, just use os.linese
Hi, not even sure if I can ask this very smartly but we shall try:
