Example of Advanced VLC Usage on Linux A screenwriter or multimedia developer can use VLC through the command line to automate video conversion or stream capture. For example:vlc input.mp4 –sout ‘#transcode{vcodec=h264,acodec=mp3}:std{access=file,mux=mp4,dst=output.mp4}’ This command converts a video to another format without a graphical interface, which is valuable for servers or remote systems. GIMP: The Power of Photoshop Accessible on Linux for All Retouchers
Whether you’re a professional graphic designer or a simple image enthusiast, GIMP stands out as an excellent graphics editor. A true free alternative to Photoshop, it offers a wide range of sophisticated tools for manipulating, retouching, creating, and composing images.
Despite an interface that can sometimes be intimidating for beginners, GIMP is remarkably flexible. Its advanced features include layers, masks, ICC profile management, RAW file support, and a wealth of filters. Many users enjoy using the G’MIC plugin, which adds a wide range of artistic filters to enhance their creations.
- A comprehensive image editor, available free of charge.
- Native support for layers, filters, and advanced tools.
- Huge library of plugins, including G’MIC for a variety of effects.
- Compatible with many image formats (JPEG, PNG, TIFF, PSD).
- Easy installation via repositories, or via Flatpak/Snap for recent versions.
Additionally, GIMP can be paired with other Linux tools for a complete graphics chain, including Inkscape for vector drawing or Darktable for RAW photo management.

Installing and starting GIMP for the first time
On most distributions, a simple command is all it takes:
vlc input.mp4 --sout '#transcode{vcodec=h264,acodec=mp3}:std{access=file,mux=mp4,dst=output.mp4}'“} –>sudo apt install gimp
. To ensure a recent version or a standalone installation, choose Flatpak:
flatpak install flathub org.gimp.GIMP
Getting started can be made easier by online tutorials covering initial configuration and basic tools. Although the interface is rich, the active community and numerous French-speaking resources contribute to rapid skill development.
Communication and management applications: Thunderbird, Bitwarden, and Discord for a secure and efficient workflow
- In a well-configured Linux system, electronic communication and digital identity management are central concerns. Here are three essential applications:
- Thunderbird
- : Open-source email client that supports POP and IMAP protocols, as well as advanced calendar and task integration, while offering GPG encryption support for secure communication.
- Bitwarden
- : Open-source password manager offering an encrypted, cross-platform vault with multi-factor authentication and TOTP (Google Authenticator) support.
Discord : Although non-Linux in origin, Discord is available via Flatpak/Snap for access to voice, text, and community communication, essential for modern Linux teams and communities. Each of these solutions integrates easily into a Linux workflow, with well-designed interfaces and a strong community behind them. For example, Thunderbird remains a long-standing benchmark because it combines robustness and compatibility with email standards. Bitwarden ensures enhanced security by centralizing passwords, a must in today’s digital age. Discord supports team collaboration, including for developers and system administrators managing Linux projects. Integrating these applications into your environment is simple: Installation via repositories or Flatpak/Snap.
