Count number of bytes in given file:

$ ./ccwc -c data/test.txt

# sample output
342190 data/test.txt

Count number of lines in given file:

$ ./ccwc -l data/test.txt

# sample output
7145 data/test.txt

Count number of chars in given file:

$ ./ccwc -m data/test.txt

# sample output
339292 data/test.txt

Count number of words in given file:

$ ./ccwc -w data/test.txt

# sample output
58164 data/test.txt

You can combine multiple count flags:

$ ./ccwc -wlm data/test.txt

# sample output
7145 58164 339292 data/test.txt

When multiple count flags are provided, the print order will always be lines, words, chars and then bytes count.

If no count flags are given, default to lines, words and bytes count:

$ ./ccwc data/test.txt

# sample output
7145 58164 342190 data/test.txt

If no file is given, default to stdin:

$ cat data/test.txt | ./ccwc

# sample output
