NAME
       ent - A pseudorandom number sequence test program

SYNOPSIS
       ent [-bcftu] files...

DESCRIPTION
       This manual page documents briefly the ent command.  This manual page was
       written for the Debian GNU/Linux distribution because the original
       program does not have a manual page.  The original documentation is in
       /usr/share/doc/ent/ent.html

       ent is a program which which applies various tests to sequences of bytes
       stored in files and reports the results of those tests.  The program is
       useful for those evaluating pseudorandom number generators for encryption
       and statistical sampling applications, compression algorithms, and other
       applications where the information density of a file is of interest.

OPTIONS
       -b     The input is treated as a stream of bits rather than of 8-bit
              bytes.  Statistics reported reflect the properties of the
              bitstream.  Show summary of options.

       -c     Print a table of the number of occurrences of each possible byte
              (or bit, if the -b option is also specified) value, and the
              fraction of the overall file made up by that value.  Printable
              characters in the ISO 8859-1 Latin1 character set are shown along
              with their decimal byte values. In non-terse output mode, values
              with zero occurrences are not printed.

       -f     Fold upper case letters to lower case before computing statistics.
              Folding is done based on the ISO 8859-1 Latin1 character set, with
              accented letters correctly processed.

       -t     Terse mode.

       -u     Print how-to-call information.
