GNOME Search Tool is a utility for finding files on your system. To perform a basic search, you can type a filename or a partial filename, with or without wildcards. To refine your search, you can apply additional search options. GNOME Search Tool uses the find, grep, and locate UNIX commands. The case sensitivity of the search depends on your operating system. For example, on Linux, the find, grep, and locate commands support the -i option, so all searches are case-insensitive.
