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.

Some of the main features of Catfish are:

• Search for files anywhere on your system, including the mounted partitions
• Search inside the files (including PDFs) for their contents (which can be enabled from preferences)
• Search within compressed files (.zip, .odt and .docx). This can be enabled from preferences.
• Search hidden files as well
• Fulltext now searches UTF-7, UTF-8, UTF-16 BE/LE, and UTF-3 BE/LE
• Refine your search based on modification time
• Refine your search based on file type (images, videos, documents etc)
• Refine your search based on location (Documents, Downloads, Pictures or other folders)
• Exclude certain directories and paths from your search
• Lightweight and simple interface
