47 | .Sh DESCRIPTION | |
48 | The | |
49 | .Nm wc | |
50 | utility reads one or more input text files, and, by | |
51 | default, writes the number of lines, words, and bytes | |
52 | contained in each input file to the standard output. | |
53 | If more than one input file is specified, | |
54 | a line of cumulative count(s) for all named files is output on a | |
55 | separate line | |
56 | following the last file count. | |
57 | .Nm Wc | |
58 | considers a word to be a maximal string of | |
59 | characters delimited by white space. | |
60 | .Pp | |
61 | The following options are available: | |
62 | .Bl -tag -width Ds | |
63 | .It Fl c | |
64 | The number of bytes in each input file | |
65 | is written to the standard output. | |
66 | .It Fl l | |
67 | The number of lines in each input file | |
68 | is written to the standard output. | |
69 | .It Fl w | |
70 | The number of words in each input file | |
71 | is written to the standard output. | |
72 | .El | |
73 | .Pp | |
74 | When an option is specified, | |
75 | .Nm wc | |
76 | only | |
77 | reports the | |
78 | information requested by that option. The | |
79 | default action is equivalent to all the | |
80 | flags | |
81 | .Fl clw | |
82 | having been specified. | |
83 | .Pp | |
84 | The following operands are available: | |
85 | .Bl -tag -width Ds | |
86 | .It Ar file | |
87 | A pathname of an input file. | |
88 | .El | |
89 | .Pp | |
90 | If no file names | |
91 | are specified, the standard input is used and | |
92 | a file name is not output. The resulting output is one | |
93 | line of the requested count(s) with the cumulative sum | |
94 | of all files read in via standard input. | |
95 | .Pp | |
96 | By default, the standard output contains a line for each | |
97 | input file of the form: | |
98 | .Bd -literal -offset indent | |
99 | lines words bytes file_name | |
100 | .Ed | |
101 | .Pp | |
102 | The counts for lines, words and bytes are integers separated | |
103 | by spaces. | |
104 | The ordering of the display of the number of lines, words, | |
105 | and/or bytes is the order in which the options were specified. | |
106 | .Pp | |
107 | The | |
108 | .Nm wc | |
109 | utility exits 0 on success, and >0 if an error occurs. | |
110 | .Sh STANDARDS | |
111 | The | |
112 | .Nm wc | |
113 | function conforms to | |
114 | .St -p1003.2 . |
