drm_tools 1.1.5 15 JUN 2006
Author: David Mathog, mathog@caltech.edu
This is a collection of small tools that are sometimes helpful in specific instances. Each is provided as source code with a man page and an html version of the man page. Included programs are:
accudate: An extended version of the unix "date" program.
If supported by the compiler and OS it has subsecond
accuracy and can easily be used to measure delta
times in scripts.
columnadd: Add columns of integers, decimals, and/or times.
datasniffer A utility for formatting binary data dumps. Handy
for reverse engineering binary data files if the
contents are either already partially known or are
expected to be intelligible upon careful examination.
extract: A utility that is designed to extract and
emit data from text files based on character
or token position. In many instances it can
replace tr, sed, or awk.
execinput: A utility that reads from stdin and executes
each line as a command in a subprocess.
mdump: A utility for formatting binary data. Handy
for decoding foreign binary data files.
msgqueue: A command line interface to create message queues
and send/receive messages.
Build instructions:
Edit the build_(OSNAME) scripts as desired and run them.
All of these programs are subject to the following license conditions which may be viewed by executing the program with the -i option:
