wc – word count|
wc [ –lwrbc ] [ file ... ]|
Wc counts lines, words, runes, syntactically–invalid UTF codes
and bytes in the named files, or in the standard input if no file
is named. A word is a maximal string of characters delimited by
spaces, tabs or newlines. The count of runes includes invalid
If the optional argument is present, just the specified counts
(lines, words, runes, broken UTF codes or bytes) are selected
by the letters l, w, r, b, or c. Otherwise, lines, words and bytes
(–lwc) are reported.
The Unicode Standard has many blank characters scattered through
it, but wc looks for only ASCII space, tab and newline. |
Wc should have options to count suboptimal UTF codes and bytes
that cannot occur in any UTF code.
