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.
