The shell tools in the fss project are developed to improve the command-line search experience. They integrate the known powerful utilities like fd, ag and pdfgrep with the fzf fuzzy finder and different preview and file opening tools to create a more user-friendly envoronment for shell-based file searching. A configuration file allows easy adaptation to various file types, preview options and opening commands. The libraries can also be easily integrated into other customized shell scripts. I hope be also beneficial and enjoyable to use for others.
