FREQ(1)FREQ(1)NAMEfreq - print histogram of character frequencies
SYNOPSISfreq [ -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
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.
