Build

make build

This will create a binary at bin/nhwc

Usage

Invoke nhwc passing in desired options followed by 0 or more files. nhwc will output how many lines, words, bytes, or character each file contains, based on options specified.

If no files are provided, nhwc will read from stdin until EOF (or ^D) and take this as input to the program.

nhwc [-c -l -m -w] [file ...]

-c will write the number of bytes in each input file to the stdout – this option will cancel out any prior usage of the -m option.

-l will write the number of lines in each input file to the stdout.

-m will write the number of characters in each input file to stdout. 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 will write the number of words in each input file to the stdout.
