<p><font size=+1><b>SYNOPSIS </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<tt><font size=+1>freq</font></tt> [ <tt><font size=+1>−dxocr</font></tt> ] [ <i>file ...</i> ]<br>
</table>
<p><font size=+1><b>DESCRIPTION </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<i>Freq</i> reads the given files (default standard input) and prints
histograms of the character frequencies. By default, <i>freq</i> counts
each byte as a character; under the <tt><font size=+1>−r</font></tt> option it instead counts
UTF sequences, that is, runes.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
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 <tt><font size=+1>−d</font></tt>, <tt><font size=+1>−x</font></tt>, <tt><font size=+1>−o</font></tt>, <tt><font size=+1>−c</font></tt> flags specify a subset
of value formats: decimal, hex, octal, and character, respectively.<br>
