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.
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.
