 801 @item binformat
 802 Format complex binary data into text.
 803 @item binload
 804 Load data into a binary file using simple commands from the input.
 805 @item binorder
 806 Sort, merge, search, retrieve or generate test data consisting of fixed size
 807 binary records.
 808 @item binreplace
 809 Find or find/replace in binary files.
 810 @item binsplit
 811 Split test data consisting of fixed size binary records into one or more
 812 output streams.
 813 @item chardiff
 814 Find changes between two files at the character level.  Unlike \"diff\", it
 815 lists just the characters that differ, so if the 40,000th character is
 816 different only that one character will be shown, not the entire line.
 817 @item columnadd
 818 Add columns of integers, decimals, and/or times.
 819 @item datasniffer
 820 A utility for formatting binary data dumps.
 821 @item dmath
 822 Double precision interactive command line math calculator.
 823 @item extract
 824 Extract and emit data from text files based on character or token position.
 825 @item execinput
 826 A utility that reads from STDIN and executes each line as a command in a
 827 sub-process.
 828 @item indexed_text
 829 A utility for rapid retrieval of text by line numbers, in any order, from a
 830 text file.
 831 @item mdump
 832 Format binary data.
 833 @item msgqueue
 834 Create message queues and send/receive messages.
 835 @item mbin
 836 @itemx mbout
 837 Multiple buffer in and out.  Used for buffering a lot of data between a slow
 838 device and a fast device.  Mostly for buffering streaming tape drives for use
 839 with slower network connections, so that streaming is maintained as much as
 840 possible to minimize wear on the tape device.
 841 @item pockmark
 842 Corrupt data streams - useful for testing error correction and data recovery.

 844 Filter, list, or split a tar file.
