NAME
wc - count words, lines, and bytes or characters in a file
SYNOPSIS
[file]...
DESCRIPTION
The command counts lines, words, and bytes or characters in the named files, or in the standard input if no file names are specified. It
also keeps a total count for all named files.
A word is a string of characters delimited by spaces, tabs, or newlines.
Options

Report the number of bytes in each input file.
Report the number of newline characters in each input file.
Report the number of characters in each input file.
Report the number of words in each input file.
The and options are mutually exclusive. Otherwise, the and or options can be used in any combination to specify that a subset of lines,
words, and bytes or characters are to be reported.
When any option is specified, reports only the information requested. If no option is specified, the default output is
When a file is specified on the command line, its name is printed along with the counts.
Standard Output
By default, the standard output contains an entry for each input file in the form:
newlines words bytes file
If the option is specified, the number of characters replaces the bytes field in this format.
If any option is specified, the fields for the unspecified options are omitted.
If no file operand is specified, neither the file name nor the preceding blank character is written.
If more than one file operand is specified, an additional line is written at the end of the output, of the same format as the other lines,
except that the word (in the POSIX locale) is written instead of a file name and the total of each column is written as appropriate.
Under UNIX Standard environment, a word is a string of characters delimited by spaces, tabs, newline, carriage-return, vertical tab, or
form-feed.
