file sizetransmission
When I add a torrent the program works fine but after a few minutes it increases the value of total size. Right now I am downloading a torrent of size 5.08 GB, but the program detects it as 5.45 GB.
What may cause that kind of problem and how do I check whether files downloaded correctly?
First, add the PPA and update if you haven't already (Close transmission first):
Command line way:
sudo add-apt-repository ppa:transmissionbt/ppa
sudo apt-get update
sudo apt-get install transmission-gtk transmission-common
Or:
Enter (change oneiric to your version if different):
deb http://ppa.launchpad.net/transmissionbt/ppa/ubuntu oneiric main
deb-src http://ppa.launchpad.net/transmissionbt/ppa/ubuntu oneiric main
Close Settings Window.
Second, Edit the Preferences in Transmission: 1. Open Transmission. 2. Open "Edit" ➜ "Prefernces". 3. Under the "Downloading" Tab, Under "Queue", set "Maximum Active Downloads" to the limit you desire.
This information isn't passed to the scripts via environment variables, so you'll need to query Transmission's RPC interface. This is sometimes done by client libraries -- for example, a Python script could use python transmissionrpc. There are other interfaces like this listed at http://www.transmissionbt.com/resources/ .
Here's a quick approach that will use transmission-remote to count the number of non-idle downloads:
transmission-remote yourhost:yourport -tall --info | grep "^ State:" | grep "Down" | wc --lines
If you want to include idle downloads too, you could try this:
transmission-remote yourhost:yourport -l | grep -v -e " 100% " -e "^Sum" -e "^ID" -e " Stopped " | wc --lines
Where "^ID" and "^Sum" strips the header and footer; " 100% " strips completed torrents; and " Stopped " strips out the incomplete-but-paused torrents. This approach isn't foolproof -- for example, a torrent named " 100% Stopped " would break it.

Are you sure the unit is the same? Maybe Transmissions is not using GiB units?
It happens, that 5.45 GB = 5.08 GiB <--- Note the "i".
The difference between GB (gigabytes) and GiB (gibibytes) is that GB are based on power of 10, and GiB are based on power of 2.
and, subsequently
GiB is not a SI unit, though SI standard recommends to use it for data size. There is a short article http://en.wikipedia.org/wiki/Gibibyte and there is a detailed explanation of this idea: http://en.wikipedia.org/wiki/Binary_prefix
Note that 5.45 GB = 5450000000 B = 5.08 GiB, so if Transmission uses GB instead of GiB, then everything is okay ;)
