wc - Counts the lines, words, characters, and bytes in a file
wc [-c|-m] [-lw] [file...]
command counts the lines, words, and characters
or bytes in a file, or in the standard input if you do not specify any files,
and writes the results to standard output. It also keeps a total count for
all named files.
Interfaces documented on this reference page conform to industry standards as follows:
wc: XPG4, XPG4-UNIX
Refer to the
reference page for more information
about industry standards and associated tags.
Counts bytes in the input.
Counts lines in the input.
Counts characters in the input.
Counts words in the input.
Specifies the pathname of the input file. If this operand
is omitted, standard input is used.
A word is defined as a string of characters delimited by white space as defined in the X/Open Base Definitions for XCU4.
The wc command counts lines, words, and bytes by default. Use the appropriate options to limit wc output. Specifying wc without options is the equivalent of specifying wc -lwc. If any options are specified, only the requested information is output.
The order in which counts appear in the output line is lines, words, bytes. If an option is omitted, then the corresponding field in the output is omitted. If the -m option is used, then character counts replace byte counts.
When you specify one or more files,
names of the files along with the counts. If standard input is used, then
no file name is displayed.
The following exit values are returned:
An error occurred.
To display the number of lines, words, and bytes in the file text, enter: wc text
27 722 text To count lines, words, and bytes in more than one file, use wc with more than one input file or with a file name pattern. For example, the following command can be issued in a directory containing the files text, text1, and text2: wc -l text*
There are 1869 characters in *.c files

is unset or null, the corresponding value from the default locale is used.
If any of the internationalization variables contain an invalid setting, the
utility behaves as if none of the variables had been defined.
If set to a non-empty string value, overrides the values of
all the other internationalization variables.
Determines the locale for the interpretation of sequences
of bytes of text data as characters (for example, single-byte as opposed to
multibyte characters in arguments and input files) and which characters are
defined as white space characters.
Determines the locale for the format and contents of diagnostic
messages written to standard error and informative messages written to standard
Determines the location of message catalogues for the processing
