elFinder is a Web-based file manager that was inspired by the simplicity and convenience of Mac OS X's Finder. It attempts to make working with remote files as convenient as working with those on your computer. It supports QuickLook for most types of files, copy/move with drag and drop, hot keys, a built-in text editor, context menus, and much more.
emv is a tool for mass-renaming files with a text editor. It can perform two pass renaming, link creation, file list splitting, and link target editing. emv logs its actions as shell-script-style mv commands in case you want to undo them. It is quite capable when used with the Vim text editor's visual block changes. emv can also be used non-interactively by providing a Perl expression for renaming files. It's especially useful if you want to see all the files at once and want to think about their names while editing and changing whole groups of files.
filegive easily sends or receives files point-to-point, with authentication and ciphering, and the other side only needs a Web browser. No third party server is involved in the transfer. It can use common NAT traversal protocols like uPnP and NAT-PMP, manually forwarded ports, or a public ssh server.
sfre (system flight recorder editor) is a script that wraps a text editor or any arbitrary command and implements logging, file locking, and change tracking for the command executed. It is meant for helping system administrators manage a system in tandem without interfering with each other.
sqlmap is a penetration testing tool that automates the process of detecting and exploiting SQL injection flaws and taking over of database servers. It comes with a detection engine, many niche features, and a broad range of switches including database fingerprinting, data fetching from the database, and accessing the underlying file system and executing commands on the operating system via out-of-band connections.
