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).
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.
PYBAG implements a portable bag and is intended for fast synchronization and backup. It lets you use a portable digital storage device to carry your electronic documents similar to the way you can use a bag to carry paper documents. You can synchronize the bag with your original files easily. If a synchronization conflict occurs, it will be reported. You can specify rules for automatic conflict resolution. With PYBAG, you can backup files and synchronize any changes made to the original files with the bag. The synchronization process will only copy changed files. The program is cross-platform and independent from the OS and filesystem. You may easily synchronize files between Windows and Linux, for example. Symbolic links are supported on all systems (if the OS or filesystem does not support symlinks, then they are emulated). This program has a GUI and a command line interface.
ChiMeRA is a configuration management tool designed around three basic concepts. The first is a framework for managing servers, allowing for command execution and file transfer over SSH. The second is a repository for managing files that enables change tracking, archiving, and management of various user definable configuration files across multiple servers through a standard revision control tool. The third concept is an aesthetic principle of simplicity, giving administrators straightforward interfaces to manage complicated environments.
tagls is a tool that matches file names using boolean expressions made of tags and regular expressions. It handles searching in file lists with word boundaries for "tags", stemming and synonym expansion for both tags and regular expressions, and boolean expressions over lists of tags or regular expressions. It can match against either the file name or the file's content. The output can be unsorted, sorted by name, or sorted by relevance.
waitcond is a script to specify a combination of events using boolean expressions over various events. It can periodically grep in files, wait for the (dis)appearance of files or processes, wait for certain CPU/net/disk idle values, or wait for an idle tty. waitcond is meant to be combined with some notification tool or system.
rlimit is a program that lets you run processes with system resource limits set. It can be used by software developers and testers to test that software will run correctly in resource restricted environments. It is also useful for software which would otherwise consume excessive resources such as programs that used 100% CPU, set their own priority levels, or consume too much memory. This is basically a command line interface to the system functions getrlimit() and setrlimit().
Qataki is a shell script that you can use to read/post notices from the command line in a simple manner. It supports Identi.ca, Twitter, and StatusNet. You can post, reply, retweet, or send direct messages; read personal, public, and user and group timelines (last statuses); read messages directed to you (i.e. where you are mentioned); read messages in context (conversations available only for Identi.ca/StatusNet); and search for notices.
