–m Prints a character count. You cannot specify this option with –c.
–w Prints a word count
The order of options can dictate the order in which wc displays counts. For
example, wc –cwl displays the number of bytes, then the number of words, then
the number of s. If you do not specify any options, the default is wc –lwc
( count, then words, then bytes).
A word is considered to be a character or characters delimited by white space.
Note: If you have a file containing doublebyte characters, the byte count is higher
than the character count.
wc uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.

1 Failure because of an inability to open the input file

The way the order of options –c, –l and –w affects the order of display is an
extension to traditional implementations of wc.

whence [–v] name ...
whence tells how the shell would interpret each name if used as a command name.
Shell keywords, aliases, functions, built-in commands, and executable files are
distinguished. For executable files, the full pathname is given. If the executable file
is a tracked alias, the string identifies it as cached.
–v Gives a more verbose report.
