NAME
       freq - print histogram of character frequencies

SYNOPSIS
       freq [ -dxocr ] [ 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.
