wc is a Unix utility tool that prints the number of lines, words or bytes in a text file. This is a relatively straight forward implementation of the tool in pure C.

You can compile the source file using gcc (GCC needs to be installed).

mkdir -p ./build
gcc -o ./build/wc ./wc.c

Alternatively, you can batch execute the commands if you have make installed.

make build

wc expects an optional flag and filepath argument.

./build/wc [-FLAG] [FILEPATH]
