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.
