wc
utility reads one or more input text files and,
by default, writes the number of lines, words, and bytes contained in each
input file to the standard output. If more than one input file is specified, a
line of cumulative count(s) for all named files is output on a separate line
following the last file count. wc
considers a word to
be a maximal string of characters delimited by whitespace. Whitespace
characters are the set of characters for which the
isspace(3) function returns true.
The options are as follows:
-c
-h
-l
-m
-w
When an option is specified, wc
only
reports the information requested by that option. The default action is
equivalent to the flags -clw
having been
specified.
If no file names are specified, the standard input is used and a file name is not output. The resulting output is one line of the requested count(s) with the cumulative sum of all files read in via standard input.
By default, the standard output contains a line for each input file of the form:
lines words bytes file_name
The counts for lines, words, and bytes (or characters) are integers separated by spaces.

-m
has the same effect as
-c
.wc
utility exits 0 on success,
and >0 if an error occurs.
wc
utility is compliant with the
IEEE Std 1003.1-2008 (“POSIX.1”)
specification.
The flag [-h
] is an extension to that
specification.
