Moosic is a music player that focuses on easy playlist management. It consists of a server process that maintains a queue of music files to play and a client program which sends commands to the server. The server continually runs through its playlist, popping items off the top of the list and playing each with an external program. The client is a simple command-line utility which allows you to perform powerful operations upon the server's queue, including the addition of whole directory trees, automatic shuffling, and item removal according to regular expressions. The server comes configured to play MP3, Ogg, MIDI, MOD, and WAV files.
PDFtk Server is a simple commandline tool for doing everyday things with PDF documents. You can use it to merge PDF documents or collate PDF page scans, split PDF pages into a new document, rotate PDF documents or pages, decrypt input as necessary (password required), encrypt output as desired, fill PDF forms with X/FDF data and/or flatten forms, generate FDF data stencils from PDF forms, apply a background watermark or a foreground stamp, report PDF metrics, bookmarks, and metadata, add/update PDF bookmarks or metadata, attach files to PDF pages or the PDF document, unpack PDF attachments, burst a PDF document into single pages, uncompress and re-compress page streams, and repair corrupted PDF files (where possible).
Binmay is a command line binary search and replace program. It allows one to specify a binary string (in hex) to search for and, optionally, a binary string to replace it with. One can mask both search and replace strings as one can mask an IP. It is handy for changing broken user SID/RIDs in ntuser.dat files after you move a profile from somewhere to somewhere else.
GoldenPod is a command line podcast client. It allows you to easily manage and download podcasts from the command line. It can download podcasts from standard RSS(-like) feeds, or it can attempt to parse any other cleartext document (XML or HTML) for a list of audio files and download those. For users already using BashPodder, it can function as a more feature-rich drop-in replacement for it.
dtrx intelligently extracts many different archive types. It will get the contents from tar, zip, rpm, deb, and cpio archives, as well as compressed files, with one simple command. It helps keep your filesystem sane by putting every archive's contents into a dedicated directory, and making sure the owner can read and write whatever's extracted. It can even recursively extract archives.
audiopreview is a command-line tool that plays previews of many audio file types (Ogg, MP3, etc.), video file types (AVI, MPEG, Real, etc.), and Internet streams. It can also be used as a regular command-line media file player (i.e. play the files entirely like yauap or mpc123 would).
