NAME
wc
- word, line, character, and byte count
SYNOPSIS
[-clmw
]
[file ...
]
DESCRIPTION
The
utility displays the number of lines, words, and bytes contained in each
input
file
or standard input (if no file is specified) to the standard output.
A line is defined as a string of characters delimited by a
Aq newline
character.
Characters beyond the final
Aq newline
character will not be included
in the line count.
A word is defined as a string of characters 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 output for
the last file.
The following options are available:
-c
The number of bytes in each input file
is written to the standard output.
This will cancel out any prior usage of the
-m
option.
-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.
If the current locale does not support multibyte characters, this
is equivalent to the
-c
option.
This will cancel out any prior usage of the
-c
option.
-w
The number of words in each input file
is written to the standard output.
When an option is specified,
only reports the information requested by that option.
The order of output always takes the form of line, word,
byte, and file name.
The default action is equivalent to specifying the
-c , l
and
-w
options.
If no files are specified, the standard input is used and no
file name is displayed.
The prompt will accept input until receiving EOF, or
Bq ^D
in most environments.
ENVIRONMENT
The
LANG , LC_ALL
and
LC_CTYPE
environment variables affect the execution of
as described in
environ(7).
EXIT STATUS
Ex -std
EXAMPLES
Count the number of characters, words and lines in each of the files
report1
and
report2
as well as the totals for both:
"wc -mlw report1 report2"
COMPATIBILITY
Historically, the
utility was documented to define a word as a
Do maximal string of
characters delimited by <space>, <tab> or <newline> characters
Dc .
The implementation, however, did not handle non-printing characters
correctly so that
`` ^D^E
''
counted as 6 spaces, while
``foo^D^Ebar
''
counted as 8 characters.
BSD 4
systems after
BSD 4.3
modified the implementation to be consistent
with the documentation.
This implementation defines a
``word''
in terms of the
iswspace(3)
function, as required by
St -p1003.2 .
