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.
