Catfish
File searching tool which is configurable via the command line
Catfish is a small, fast, and powerful file search utility. Featuring a minimal interface with an emphasis on results, it helps users find the files they need without a file manager. With powerful filters such as modification date, file type, and file contents, users will no longer be dependent on the file manager or organization skills.
Catfish is a handy file searching tool for Linux and UNIX. The interface is intentionally lightweight and simple, using only Gtk+3. You can configure it to your needs by using several command line options.
