Gpart is a small tool which tries to guess which partitions are on a PC harddisk in case the primary partition table was damaged. It works by scanning through the device (or file) given on the commandline on a sector basis. Each guessing module is asked if it thinks a filesystem it knows about could start at a given sector. Several filesystem guessing modules are built in, and others can be added dynamically.
The Exquisite `df' (xdf) is a souped-up version of df(1) rewritten from scratch and focused on flexibility of field selection and output format. It offers HTML and CSV outputs, besides the traditional text-based console output. It is fit for system administrators who are tired of post-processing df(1) output through shell or Perl scripts in order to avoid broken lines or to get a simple total/summary line.
xMarkup is a command line and GUI utility for multipurpose processing of a set of text files. It can be used to generate or edit the navigational cross-references within a set of HTML documents, analyze and convert the structure or content of SGML, XML, HTML, or text documents, split or merge text files with specified rules, analyze and extract data, generate scripts, and more. xMarkup supports a built-in procedural language which may be used to describe rules of the processing. This language is a simple dialect of the Icon programming language.
