Top 5 Torrent Clients For Ubuntu Linux
================================================================================
![Best Torrent clients for Ubuntu Linux](http://itsfoss.itsfoss.netdna-cdn.com/wp-content/uploads/2015/08/5_Best_Torrent_Ubuntu.png)
Looking for the **best torrent client in Ubuntu**? Indeed there are a number of torrent clients available for desktop Linux. But which ones are the **best Ubuntu torrent clients** among them?
I am going to list top 5 torrent clients for Linux, which are lightweight, feature rich and have impressive GUI. Ease of installation and using is also a factor.
### Best torrent programs for Ubuntu ###
Since Ubuntu comes by default with Transmission, I am going to exclude it from the list. This doesn’t mean that Transmission doesn’t deserve to be on the list. Transmission is a good to have torrent client for Ubuntu and this is the reason why it is the default Torrent application in several Linux distributions, including Ubuntu.
----------
### Deluge ###

[Deluge][1] has been chosen as the best torrent client for Linux by Lifehacker and that speaks itself of the usefulness of Deluge. And it’s not just Lifehacker who is fan of Deluge, check out any forum and you’ll find a number of people admitting that Deluge is their favorite.
Fast, sleek and intuitive interface makes Deluge a hot favorite among Linux users.
Deluge is available in Ubuntu repositories and you can install it in Ubuntu Software Center or by using the command below:
sudo apt-get install deluge
----------
### qBittorrent ###
![qBittorrent client for Linux](http://itsfoss.itsfoss.netdna-cdn.com/wp-content/uploads/2015/08/qbittorrent_icon.png)
As the name suggests, [qBittorrent][2] is the Qt version of famous [Bittorrent][3] application. You’ll see an interface similar to Bittorrent client in Windows, if you ever used it. Sort of lightweight and have all the standard features of a torrent program, qBittorrent is also available in default Ubuntu repository.
It could be installed from Ubuntu Software Center or using the command below:
sudo apt-get install qbittorrent
----------
### Tixati ###
![Tixati torrent client logo](http://itsfoss.itsfoss.netdna-cdn.com/wp-content/uploads/2015/08/tixati_icon.png)
[Tixati][4] is another nice to have torrent client for Ubuntu. It has a default dark theme which might be preferred by many but not me. It has all the standard features that you can seek in a torrent client.
In addition to that, there are additional feature of data analysis. You can measure and analyze bandwidth and other statistics in nice charts.
- [Download Tixati][5]
----------
### Vuze ###
![Vuze Torrent Logo](http://itsfoss.itsfoss.netdna-cdn.com/wp-content/uploads/2015/08/vuze_icon_for_mac_os_x_by_hamzasaleem-d6yx1fp.png)
[Vuze][6] is favorite torrent application of a number of Linux as well as Windows users. Apart from the standard features, you can search for torrents directly in the application. You can also subscribe to episodic content so that you won’t have to search for new contents as you can see it in your subscription in sidebar.
It also comes with a video player that can play HD videos with subtitles and all. But I don’t think you would like to use it over the better video players such as VLC.
Vuze can be installed from Ubuntu Software Center or using the command below:
sudo apt-get install vuze
----------
### Frostwire ###
![Logo of Frostwire torrent client](http://itsfoss.itsfoss.netdna-cdn.com/wp-content/uploads/2015/08/frostwire.png)
[Frostwire][7] is the torrent application you might want to try. It is more than just a simple torrent client. Also available for Android, you can use it to share files over WiFi.
You can search for torrents from within the application and play them inside the application. In addition to the downloaded files, it can browse your local media and have them organized inside the player. The same is applicable for the Android version.
An additional feature is that Frostwire also provides access to legal music by indi artists. You can download them and listen to it, for free, for legal.
- [Download Frostwire][8]
----------
### Honorable mention ###
On Windows, uTorrent (pronounced mu torrent) is my favorite torrent application. While uTorrent may be available for Linux, I deliberately skipped it from the list because installing and using uTorrent in Linux is neither easy nor does it provide a complete application experience (runs with in web browser).
You can read about uTorrent installation in Ubuntu [here][9].
#### Quick tip: ####
Most of the time, torrent applications do not start by default. You might want to change this behavior. Read this post to learn [how to manage startup applications in Ubuntu][10].
### What’s your favorite? ###
That was my opinion on the best Torrent clients in Ubuntu. What is your favorite one? Do leave a comment. You can also check the [best download managers for Ubuntu][11] in related posts. And if you use Popcorn Time, check these [Popcorn Time Tips][12].

Linux FAQs with Answers--How to count the number of threads in a process on Linux
================================================================================
> **Question**: I have an application running, which forks a number of threads at run-time. I want to know how many threads are actively running in the program. What is the easiest way to check the thread count of a process on Linux?
If you want to see the number of threads per process in Linux environments, there are several ways to do it.
### Method One: /proc ###
The proc pseudo filesystem, which resides in /proc directory, is the easiest way to see the thread count of any active process. The /proc directory exports in the form of readable text files a wealth of information related to existing processes and system hardware such as CPU, interrupts, memory, disk, etc.
$ cat /proc/<pid>/status
The above command will show detailed information about the process with <pid>, which includes process state (e.g., sleeping, running), parent PID, UID, GID, the number of file descriptors used, and the number of context switches. The output also indicates **the total number of threads created in a process** as follows.
Threads: <N>
For example, to check the thread count of a process with PID 20571:
$ cat /proc/20571/status
![](https://farm6.staticflickr.com/5649/20341236279_f4a4d809d2_b.jpg)
The output indicates that the process has 28 threads in it.
Alternatively, you could simply count the number of directories found in /proc/<pid>/task, as shown below.
$ ls /proc/<pid>/task | wc
This is because, for every thread created within a process, there is a corresponding directory created in /proc/<pid>/task, named with its thread ID. Thus the total number of directories in /proc/<pid>/task represents the number of threads in the process.
### Method Two: ps ###
If you are an avid user of the versatile ps command, this command can also show you individual threads of a process (with "H" option). The following command will print the thread count of a process. The "h" option is needed to hide the header in the top output.
$ ps hH p <pid> | wc -l
If you want to monitor the hardware resources (CPU & memory) consumed by different threads of a process, refer to [this tutorial][1].(注：此文我们翻译过)
