Overview

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.

Synopsis:

freq [-rdxoc] [FILES]...

Description:

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.

Options:

–r: treat input as UTF-8
–d: print decimal value
–x: print hex value
–o: print octal value
–c: print character/UTF value
