wc - display a count of lines, words and characters in a file
wc [ -c | -m | -C ] [ -lw ] [ file ... ]
SUNWcsu
The wc utility reads one or more input files and, by default, writes
the number of newline characters, words and bytes contained in each input
file to the standard output.
The utility also writes a total count for all
named files, if more than one input file is specified.
wc considers a word
to be a non-zero-length string of characters delimited by white space (for
example, SPACE
, TAB
). See iswspace(3I)
or isspace(3C)
.
The following
options are supported:
- -c
- Count bytes.
- -m
- Count characters.
- -C
- Same as -m.
- -l
- Count
lines.
- -w
- Count words delimited by white space characters or new line characters.
Delimiting characters are Extended Unix Code (EUC) characters from any
code set defined by iswspace().
If no option is specified the default is
-lwc (count lines, words, and bytes.)
The following operand is supported:
- file
- A path name of an input file. If no file operands are specified, the
standard input will be used.
