a2b invokes conversion tools in sequence to convert files from one type to another, possibly performing some extra processing along the way. Itis a wrapper for many programs like gif2png, latex2html, netpbm, mencoder, ffmpeg, oggenc, etc., that can convert content from one type to another. It can covert text, documents, images, audio, and video and more. Some examples: a2b test.mp3 test.ogg; mencoder_opts="-ss 60 -endpos 10" a2b video.avi clip.flv; a2b -g=subtitles dvd://8 movie.sub; a2b -q http://sam.nipl.net/ sam.aac. That last example downloads the author's Web page, converts it to text with lynx -dump, speaks the text with flite or espeak, and converts the audio file to AAC with faac.
Alv verifies Oracle archive logs to ensure there is a viable set available for DB recovery. It can be run from wherever the logs are stored, so verification may be offloaded from the DB server. Checks are made on file size and type. By default, the checksum of each redo record is also verified. Program output consists of log sequence numbers and character codes which indicate status and highlight any gaps. Environment variable settings allow for custom log name formats and to check the DBNAME set within a log.
AstroStack is an easy-to-use astronomical imaging and processing tool geared towards the use of inexpensive webcam CCDs. It provides a very tunable environment to produce the best quality images. It supports the following features: tunable webcam sampling; image stacking (averaging, additive etc.); pre and post-capture gamma (brightness) and contrast correction; dark-shot CCD calibration (subtractive); and an internal 16-bit grey-scale format for optimal resolution.
The Auto Screenshot Utility for Linux allows users to capture screenshots at regular intervals. Configurable options allow control of the number of screenshots to capture. The capture time interval is also configurable from the main screen of the software. If your desktop environment supports a notification area, you can even minimize the main screen of the software to the notification area/system tray. The screenshot location is configurable as well.
Backshift is a deduplicating (variable-sized, content-based blocks), compressing (xz or bz2) backup program. Full saves and incrementals are pretty indistinct other than the amount of data transmitted, somewhat like with "rsync --link-dest" but without the huge number of hardlinks. It also de-duplicates large file content at a granularity of about 2 megabytes on average; there tends to be a unique copy of each file with size less than around 2 megabytes on average.
Chnorm is a simple command line utility for setting the owner, group, and the mode of given files and directories on a per file/per directory basis, recursively. It is especially useful if you often copy files with brain-dead permissions from filesystems not supporting the Unix permission scheme. It detects executables based on their contents and sets their permissions accordingly.
Japplis Toolbox is a compilation of text utilities in one application. It can encode and decode URL, Base64, Hex, SoundEx, or Metaphone. It can convert numbers from/to binary, octal, decimal, and hexadecimal, and to date. It gives you text information such as character count, word count, MD5, or SHA. You can get Java system properties, environment variables, or Swing default values. It checks and finds regular expressions. It can also manipulate lines of text by sorting, reversing, shuffling, deleting duplicates, trimming spaces, or numbering lines.
