wc

wc(1)								   User Commands							     wc(1)

NAME

       wc - display a count of lines, words and characters in a file

SYNOPSIS

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

DESCRIPTION

       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(3C)	or
       isspace(3C).

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) char-
		acters 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 will be used.

USAGE

       See largefile(5) for the description of the behavior of wc when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect the execution of wc:	LANG,  LC_ALL,	LC_CTYPE,  LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
