drm_tools contains several small utilities: accudate, binreplace, columnadd, datasniffer, dmath, execinput, extract, mbin, mbout, mdump, and msgqueue. accudate is a date replacement with subsecond accuracy. binreplace searches and replaces in binary files. columnadd adds integers, decimals, and/or times in columns. dmath is a double precision calculator. execinput executes commands one at a time from stdin. extract extracts and then formats data from files; it supports PCRE patterns, math operations, and scripting. datasniffer and mdump format binary data files. mbin with mbout buffers large binary data streams to minimize wear on tape devices. msgqueue provides command line control of message queues.
