FREQ(1)                     General Commands Manual                    FREQ(1)



NAME
       freq - print histogram of character frequencies

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

DESCRIPTION
       Freq  reads  the  given  files (default standard input) and prints his‐
       tograms of the character frequencies.  By  default,  freq  counts  each
       byte  as  a  character;  under  the -r option it instead counts UTF se‐
       quences, 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.
