This manual page documents the GNU version of wc. wc counts the number of bytes, whitespace-separated words, and newlines in each given file, or the standard input if none are given or when a file named `-' is given. It prints one line of counts for each file, and if the file was given as an argument, it prints the filename following the counts. If more than one filename is given, wc prints a final line containing the cumulative counts, with the filename `total'. The counts are printed in the order: lines, words, bytes.
By default, wc prints all three counts. Options can specify that only certain counts be printed. Options do not undo others previously given, so wc --bytes --words prints both the byte counts and the word counts.
