Or: wc [options]... -- files0-from=F prints the number of newline characters, words, and bytes per line, and if there is more than one file, the total number of lines per line. If there is no file, or if the file location is represented by a "-", the standard stream is read. A word is a non-zero-length sequence of characters separated by blank characters. The operations below may be used to select some type of print, usually in the order of newline characters, words, characters, bytes, maximum line length-c,-- bytes print bytes-m,-- chars print characters-l,-- lines print line feeds. That is, the total number of lines-the files0-from= file reads the name terminated by NUL from the specified file, if the file is specified as "-", the file name is read from the standard input-L,-- max-line-length displays the length of the longest line-w,-- words displays the word count-- help displays this help information and exits-- version displays version information and exits.
