     FREQ(1)                                                   FREQ(1)

     NAME
          freq - print histogram of character frequencies

     SYNOPSIS
          freq [ -cdorx ] [ file ... ]

     DESCRIPTION
          Freq reads the given files (default standard input) and
          prints histograms of the character frequencies.  By default,
          freq counts each byte as a character; under the -r option it
          instead counts UTF sequences, that is, runes.

          Each non-zero entry of the table is printed preceded by the
          byte value, in decimal, octal, hex, and Unicode character
          (if printable).  If any options are given, the -d, -x, -o,
          -c flags specify a subset of value formats: decimal, hex,
          octal, and character, respectively.
