Implement progress bar in rsync

[alessandrobessi]

It would be useful to have a progress bar in rsync. The following code partially solves the problem

from tqdm import tqdm
for stdout_line in tqdm(iter(popen.stdout.readline, "")):
    ...

Indeed, when tqdm is applied to iterators it just shows the number of iterations per second and the elapsed time, unless you specify the parameter total indicating the expected number of iterations.

One could estimate the number of files contained in the src folder, and use the following code:

import os
from tqdm import tqdm
num_files = len([f for f in os.listdir(src) if os.path.isfile(os.path.join(src, f))])
for stdout_line in tqdm(iter(popen.stdout.readline, ""), total=num_files):
    ...

What do you think?

Actually I think there is a simpler solution: https://stackoverflow.com/questions/7157973/monitoring-rsync-progress#7272339

I'll have a look!
