exifprobe

Exifprobe reads image files produced by digital cameras (including several so-called "raw" file formats) and reports the structure of the files and the auxilliary data and metadata contained within them. In addition to TIFF, JPEG, and EXIF, the program understands several formats which may contain "raw" camera data, including MRW, CIFF/CRW, JP2/JPEG2000, RAF, and X3F, as well as most most TIFF-derived "raw" formats, including DNG, ORF, CR2, NEF, K25/KDC/DCR, and PEF.

MakerNote sections found in Exif IFDs are reported and expanded if the note is in a semblance of TIFF IFD format. Information which has been published on the internet is used to interpret notes where possible.

Art and Tartools
A suite of interactive tools for creation and manipulation of multi-fileset, multi-volume archives compatible with Unix and (mostly) GNU tar. You can change things (e.g. output verbosity) while the process is running, archives are automatically labeled, etc... In additon to art, you get creatar, listar, extractar, cmptar, appentar, updatar, rmtar, and mvtar. Check the DESCRIPTION for more info.
prcolumn/charcol
Prcolumn and charcol are tools for making vertical slices thru text. Prcolumn operates upon whitespace-separated columns, while charcol treats each character position as a column. Far more useful than it may appear... see the README for examples.
trim
A simple tool to trim leading or trailing whitespace and/or blank lines from text files.
bkup
A tool for making and managing "backup" copies of Unix files. Backup copies may be "temporary" (to be removed at intervals by a daemon) or "permanent" (to be removed only upon command).
