GNU Midnight Commander is a visual file manager, licensed under GNU General Public License and therefore qualifies as Free Software. It's a feature rich full-screen text mode application that allows you to copy, move and delete files and whole directory trees, search for files and run commands in
... [More] the subshell. Internal viewer and editor are included.
Midnight Commander is based on versatile text interfaces, such as Ncurses or S-Lang, which allows it to work on a regular console, inside an X Window terminal, over SSH connections and all kinds of remote shells. [Less]
GnomeVFS is a library that allows applications to transparently access various types of filesystems through a uniform interface. GnomeVFS modules include support for things such as WebDAV, ftp, local filesystem, gzip, bzip2, cdda, and others. GNOME VFS is currently used as one of the foundations of the Nautilus file manager
DragonFly BSD is a UNIX-like operating system that has been continuously developed since it forked from FreeBSD 4.8 in 2004. The development focus is on innovation and performance, as well as usability.
Nearly 22,000 third-party software packages are available due to the Ports Collection it
... [More] shares with FreeBSD (known as DPorts). Currently only the x86_64 architecture is officially supported. [Less]
Inferno® is a distributed operating system, originally developed at Bell Labs, but now developed and maintained by Vita Nuova® as Free Software. Applications written in Inferno's concurrent programming language, Limbo, are compiled to its portable virtual machine code (Dis), to run anywhere on a
... [More] network in the portable environment that Inferno provides. Unusually, that environment looks and acts like a complete operating system.
The use of a high-level language and virtual machine is sensible but mundane. The interesting thing is the system's representation of services and resources. They are represented in a file-like name hiearchy. Programs access them using only the file operations open, read/write, and close. The 'files' may of course represent stored data, but may also be devices, network and protocol interfaces, dynamic data sources, and services. The approach unifies and provides basic naming, structuring, and access control mechanisms for all system resources. A single file-service protocol (called Styx or 9P2000) makes all those resources available for import or export throughout the network in a uniform way, independent of location. An application simply attaches the resources it needs to its own per-process name hierarchy ('name space').
The system can be used to build portable client and server applications. It makes it straightforward to build lean applications that share all manner of resources over a network, without the cruft of much of the 'Grid' software one sees.
Inferno can run 'native' on various ARM, PowerPC, SPARC and x86 platforms but also 'hosted', under an existing operating system (including FreeBSD, Irix, Linux, MacOS X, Plan 9, and Solaris), again on various processor types. [Less]
Worker is a file manager for the X Window System with the classical two panel interface. It features a fully graphical configuration, external program integration through buttons and hotkeys and configurable filetype commands.
PySite is a system to manage and design multiple websites.
PySite is not a CMS in the traditional sense. Rather, you manage the contents of a website via a filemanager interface, which gives you access to all settings, the pages, the styles, plugins, etc. Compose your pages with Jinja templates
... [More], and edit your code comfortably with syntax highlighting in the ACE editor or, wysiwyg style with Aloha. You may write your stylesheets in Sass and let the integrated compiler write CSS files.
PySite also contains a facility to manage virtual mailboxes, in case you maintain your own SMTP and IMAP server, e.g. with Postfix and Dovecot. [Less]
