command-definition.wc.html Maven / Gradle / Ivy
The wc utility reads from the input and, by default, writes the
number of lines, words, and characters to the output. If more than one input
file is specified, a line of cumulative counts for all the files is displayed on
a separate line after the output for the last file.
The wc utility considers a word to be a non-zero-length string of characters
delimited by white space. White space characters are the set of characters for
which {@link Character#isWhitespace(char)} returns true.
When any option is specified, wc reports only the information requested by
the specified options.
If only one count type is requested, the count is outputted as an integer. If
more than one count is requested, a fixed width formatting is used, with the
counts being right aligned. The width of each field is equal to the width of
the widest field (count) plus two characters.
