I'm trying to get more of the low-hanging fruit of the GNUish 2.0
project done. This time, it's wc, the word-counting program.

wc - print the number of bytes, words, and lines in files
The wc program counts the number of bytes, whitespace-separated words,
and newlines in a given file, or the standard input if none are given or
when a file named '-' is given. It prints one line of counts for each
file, and if the file was given as an argument, it prints the filename
following the counts. If more than one filename is given, wc prints a
final line containing the cumulative counts, with the filename 'total'.
The counts are printed in the order: lines, words, characters (if
specified), bytes, the maximum number of characters in a line.
By default, wc prints all three counts. Options can specify that only
certain counts be printed. Options do not undo others previously given,
so wc --bytes --words prints both the byte counts and word counts.
COMPILING:
On a Cygwin installation, it's as easy as
./configure;make;make install
Other systems may differ. One may have to modify config.h (provided), then
individually compile wc.c and getopt.c. Then load them into an executable.
OPTIONS:
-c, --bytes Print only the byte counts.
-l, --lines Print only the newline counts.
-m, --chars Print only the character counts.
-w, --words Print only the word counts.
-L, --max-line-length Print only the maximum line width of a file.
Tabs are considered to be moving the column
to a multiple of 8; nonprintable characters
have a width of zero.
--files0-from=FILE Get the filenames from a file instead of the
command line. Within the file, the
names are
delimited with null characters. This option
is useful with the output of the find
command
with the -print0 option.
--help Print a usage message and exit with a
non-zero status.
--version Print version information on standard output
then exit.
