wc - print the number of bytes, words, and lines in files
wc [ options ] [file ...]
reads one or more input files and, by default, for each file writes a line containing the number of newlines, word
and bytes contained in each file followed by the file name to standard output in that order. A word
is defined to be a
non-zero length string delimited by isspace(3)
If more than one file is specified, wc writes a total count for all of the named files with total written instead of
the file name.
By default, wc writes all three counts. Options can specified so that only certain counts are written. The options -c
and -m are mutually exclusive.
If no file is given, or if the file is -, wc reads from standard input and no filename is written to
standard output. The start of the file is defined as the current offset.
