    pub chars: bool,
    pub lines: bool,
    pub words: bool,
    pub json: bool,
    pub files: Vec<PathBuf, Global>,
}

Print newline, word, and byte counts for each file.

Fields

bytes: bool

Print the byte counts

chars: bool

Print the character counts (input is interpreted as UTF-8).

lines: bool

Print the line count.

words: bool

Print the word count.

json: bool

Output result as JSON.

files: Vec<PathBuf, Global>

Files to read, if not specified, standard input is read.
