fsel
fsel (fast select) is a fast terminal-based application launcher and fuzzy finder for GNU/Linux and BSD systems, written in Rust. It provides an efficient TUI for quickly launching applications, files, and commands via fuzzy search. Type to filter results, use arrow keys to navigate, and press Enter to execute. Key features include dmenu replacement mode for piping input from stdin, which makes it compatible with existing shell scripts and workflows. It also offers a clipboard history mode when used with cclip, supporting native inline image previews in terminals like Kitty or those with Sixel and Halfblocks graphics support. fsel requires Rust stable to build and any terminal emulator to run. It can be installed via Nix flakes, Cargo, the AUR on Arch Linux, the Void Linux unofficial repository, or by building from source. Configuration is available through environment variable overrides, allowing users to customize behavior without modifying source code.
