HTMLDOC converts HTML files and Web pages into indexed HTML, PostScript, and PDF files suitable for online viewing and printing. It can be used as a standalone GUI application, in a batch document processing environment, as a Web-based report generation application, or in embedded environments to support printing of HTML content. It runs on all Unix platforms as well as Mac OS X and Windows 2000 and higher.
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.
txt2pdf PRO is a very flexible and powerfu program that converts files from text to PDF format. It extends txt2pdf with features such as the ability to add form feeds, to skip the first form feed, to set the top and left margins, to use images (JPEGs) in the background, and to create compressed PDFs.
Vim is an almost fully-compatible version of the Unix editor Vi. Many new features have been added including multi-level undo, syntax highlighting, commandline history, online help, filename completion, and block operations. It is descended from the vi clone "stevie" and runs on many systems, including Unix, MS Windows, OS/2, Macintosh, VMS, and Amiga.
rtf2latex2e is an utility to convert RTF files from popular word processors to the LaTeX2e format for those who value quality typesetting. rtf2latex2e uses the RTF reader package by Paul DuBois to parse the RTF code and generates an appropriate LaTeX file. The main features of rtf2latex2e are: detects text style: bold, italic, color, big, small,... reads embedded figures: PICT, WMF, PNG, JPEG,... reads tables: simple to semi- complex equations: reads out Equation Editor equations (courtesy Steve Swanson, http://www.mackichan.com) symbols: converts most greek and math symbols reads footnotes (not in tables yet), and converts hypertext links using the hyperref package.
Change is a non-interactive text editor, similar to sed, but much easier to use. It works by substituting a specified target pattern in the source text with another specified text pattern. It can operate on multiple files specified on the command line, or it can operate upon stdin/stdout in filter mode.
compare is similar to cmp but faster and with better readable output. compare examines one file and standard in, or two files on a byte by byte basis, and prints the file position of the first difference it finds, first in decimal and then in hexadecimal, followed by the differing byte content in hexadecimal and a quoted character.
