a handful of CLI tools that makes my life easier. Here are some of them.
cURL ( stands for Client URL) is a software that provides a library libcurl and command-line tool curl. The features and support that it provides are way overwhelming, there are so many options that can be passed to it, sometimes you are just lost in the man page.
This article aims at providing the commands that are frequently used and as a handy reference and is specific to HTTP/HTTPS protocols. This is no replacement to the man page, it’s more like the highlights of it.

Glances is a cross-platform monitoring tool which aims to present a maximum of information in a minimum of space through a curses or Web based interface. It can adapt dynamically the displayed information depending on the terminal size.
It can also work in client/server mode. Remote monitoring could be done via terminal, Web interface or API (XMLRPC and RESTful).
Glances is written in Python and uses the psutil library to get information from your system.
Stats can also be exported to external time/value databases.

Test a new operating system
Welcome to DistroTest.net
On our website you will find many operating systems,
which you can test directly online without a installation.
There are no restrictions for the operating system:
You can use all functions of the system,
Uninstall and install software, test installed programs and
even delete or format the hard disk or system files...

rmlint finds space waste and other broken things on your filesystem and offers to remove it.
There's an old saying, "anything worth doing, is worth automating"—or something like that. Downloading and reading Linux Journal always has been worth doing, and now you can automate it with our new autolj script, which you can get here.

fd is a simple, fast and user-friendly alternative to find. While it does not seek to mirror all of find's powerful functionality, it provides sensible (opinionated) defaults for 80% of the use cases.
Features
Convenient syntax: fd PATTERN instead of find -iname '*PATTERN*'.
Colorized terminal output (similar to ls).
It's fast (see benchmarks below).
Smart case: the search is case-insensitive by default. It switches to case-sensitive if the pattern contains an uppercase character*.
Ignores hidden directories and files, by default.
Ignores patterns from your .gitignore, by default.
Regular expressions.
Unicode-awareness.
The command name is 50% shorter* than find :-).
Parallel command execution with a syntax similar to GNU Parallel.

Ever wanted to record whatever you played on your speakers directly to an MP3 file? Out of the three operating systems, Linux has the most fool-proof process (by way of the Pulse Audio sound server). This sound server, though initially unpopular, is now almost universally praised. In fact, it can perform some advanced functions and can be manipulated to do almost anything you could possibly think of.
Recording system audio is done by combining two awesome Linux programs. The first being Pulse Audio Volume Control. The second is Audacity. Both programs should be in your distributions software repository.

Keep track of your system's uptime and downtime with the tuptime tool.
Finding your system's uptime is easy if the "beginning" means the last startup; the historical uptime command reports that information. But what happens if by "beginning" you mean the first startup ever of the system? Or the last 365 days? Or the last month?
Is there any way to have an accumulated uptime—or even better, a look at the whole system's life? For example, cars have odometers, and you can see the miles/kilometers since the first day. For computers, a tool was developed exactly for this task: tuptime.
tuptime reports the historical and statistical running and stopped time of your system, keeping track between restarts.

The biggest advantage of LVM over traditional disk partitions is its support for "dynamic partitions"; you can create and resize (grow or shrink) LVM volumes dynamically as needed. There is no notion of physical disk boundary in LVM logical volumes, so you can create a large LVM volume that spans across multiple smaller physical disks. Such flexible partitioning allows you to manage storage space more efficiently as disk usage patterns change over time.
If you want to add new disks to an existing LVM volume to expand its size, you can easily do it, and here is how.

Brief: Tiwo discusses the best video editors for Linux, their pros and cons and the installation method for Ubuntu-based distros in this article.
Ultra high definition or 4K footage is becoming more popular every year. But not every free video editor supports it yet. In this list we’re going to take a look at some of the best free video editing software with 4K support.
Cet ouvrage a été rédigé simplement afin que tous puissent accéder au monde merveilleux d'iptables. Il n'a jamais été destiné à rassembler des informations de bogues de sécurité sur Iptables ou Netfilter. Si vous trouvez des bogues ou des comportements insolites dans iptables ou une de ses composantes, vous devriez contacter la liste de diffusion de Netfilter et signaler le problème. On vous informera alors de la validité d'un bogue et de son éventuelle correction. Il y a très rarement de véritables bogues de sécurité identifiés dans Iptables ou Netfilter, malgré tout, un ou deux peuvent se faufiler de temps en temps. Ils sont mis en évidence sur la page principale du site de Netfilter, et c'est là que vous devriez vous rendre pour rassembler de l'information sur ce sujet.
En dehors des distributions Linux les plus connues, comme Ubuntu, Red Hat ou Fedora, il en existe d'autres moins renommées mais qui valent quand même le détour. Zoom sur les plus originales voire décalées.
eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux. You can use it to encrypt partitions and also directories that don't use a partition of their own, no matter the underlying filesystem, partition type, etc. This tutorial shows how to use eCryptfs to encrypt a directory on Debian Jessie.
reedesktop.org is open source / open discussion software projects working on interoperability and shared technology for X Window System desktops. The most famous X desktops are GNOME and KDE, but developers working on any Linux/UNIX GUI technology are welcome to participate.
freedesktop.org is building a base platform for desktop software on Linux and UNIX. The elements of this platform have become the backend for higher-level application-visible APIs such as Qt, GTK+, XUL, VCL, WINE, GNOME, and KDE. The base platform is both software and specifications.
