44.Sh SYNOPSIS
45.Nm
46.Op Fl clw
47.Op Ar
48.Sh DESCRIPTION
49The
50.Nm
51utility displays the number of lines, words, and bytes contained in each
52input
53.Ar file
54(or standard input, by default) to the standard output.
55A line is defined as a string of characters delimited by a <newline>
56character,
57and a word is defined as a string of characters delimited by white space
58characters.
59White space characters are the set of characters for which the
60.Xr isspace 3
61function returns true.
62If more than one input file is specified, a line of cumulative counts
63for all the files is displayed on a separate line after the output for
64the last file.
65.Pp
66The following options are available:
67.Bl -tag -width Ds
68.It Fl c
69The number of bytes in each input file
70is written to the standard output.
71.It Fl l
72The number of lines in each input file
73is written to the standard output.
74.It Fl w
75The number of words in each input file
76is written to the standard output.
77.El
78.Pp
79When an option is specified,
80.Nm
81only reports the information requested by that option.
82The default action is equivalent to specifying all of the flags.
83.Pp
84If no files are specified, the standard input is used and no
85file name is displayed.
86.Sh DIAGNOSTICS
87The
88.Nm
89utility exits 0 on success, and >0 if an error occurs.
90.Sh SEE ALSO
91.Xr isspace 3
92.Sh COMPATIBILITY
93Historically, the
94.Nm
95utility was documented to define a word as a ``maximal string of
96characters delimited by <space>, <tab> or <newline> characters''.
97The implementation, however, didn't handle non-printing characters
98correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar''
99counted as 8 characters.
