NAME
wc -- word, line, and byte count SYNOPSIS
wc [-c | -m] [-Llw] [file ...] DESCRIPTION
The wc utility displays the number of lines, words, bytes and characters contained in each input file (or standard input, by default) to the standard output. A line is defined as a string of characters delimited by a <newline> character, and a word is defined as a string of char- acters delimited by white space characters. White space characters are the set of characters for which the iswspace(3) function returns true. If more than one input file is specified, a line of cumulative counts for all the files is displayed on a separate line after the out- put for the last file. The following options are available: -c The number of bytes in each input file is written to the standard output. -L The number of characters in the longest line of each input file is written to the standard output. -l The number of lines in each input file is written to the standard output. -m The number of characters in each input file is written to the standard output. -w The number of words in each input file is written to the standard output. When an option is specified, wc only reports the information requested by that option. The default action is equivalent to all the flags -clw having been specified. The following operands are available: file A pathname of an input file. If no file names are specified, the standard input is used and no file name is displayed. By default, the standard output contains a line for each input file of the form: lines words bytes file_name EXIT STATUS
The wc utility exits 0 on success, and >0 if an error occurs. SEE ALSO
iswspace(3) COMPATIBILITY
Historically, the wc utility was documented to define a word as a ``maximal string of characters delimited by <space>, <tab> or <newline> characters''. The implementation, however, didn't handle non-printing characters correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar'' counted as 8 characters. 4BSD systems after 4.3BSD modified the implementation to be consistent with the documentation. This implementation defines a ``word'' in terms of the iswspace(3) function, as required by IEEE Std 1003.2 (``POSIX.2''). The -L option is a non-standard extension, compatible with the -L option of the GNU and FreeBSD wc utilities. STANDARDS
The wc utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). BSD

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
