SYNOPSIS
/usr/bin/wc wc [

-C] [
-lw] [
file]...
ksh93 wc [
-c |
-m |

-lLqw] [
file]...
DESCRIPTION
/usr/bin/wc wc 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.
wc 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(3C) or
isspace(3C).
ksh93 The
wc built-in in
ksh93 is associated with the
/bin and
/usr/bin paths.
It is invoked when
wc is executed without a pathname prefix and the
pathname search finds a
/bin/wc or
/usr/bin/wc executable.
wc reads one or more input files and, by default, for each file writes a
line containing the number of NEWLINEs, words, and bytes contained in
each file followed by the file name to standard output in that order. A
word is defined to be a
non-zero length string delimited by
isspace(3C) characters.
If more than one file is specified,
wc writes a total count for all of
the named files with total written instead of the file name.
By default,
wc writes all three counts. Options can specified so that
only certain counts are written. The
-c,
-C, and
-m options are mutually
exclusive.
If no file is specified, or if the file is
-,
wc reads from standard
input and no filename is written to standard output. The start of the
file is defined as the current offset.
-c --bytes | chars List the byte counts.
-l --lines List the line counts.
-L --longest-line | max-line-length List the longest line length.
-m | C --multibyte-chars List the character counts.
-q --quiet Suppress invalid multi-byte character warnings.
-w --words List the word counts.
OPTIONS
The following options are supported:
-c Counts bytes.
-C Same as
-m.
-l Counts lines.
-m Counts characters.
-w Counts 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 (counts lines, words, and
bytes.)
OPERANDS
The following operand is supported:
file A path name of an input file. If no
file operands are specified,
the standard input is used.
USAGE
See
largefile(7) for the description of the behavior of
wc when
encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

LC_MESSAGES, and
NLSPATH.
EXIT STATUS
0 Successful completion.
