This challenge was to build my own version of the Unix command line tool wc!
This cli tool is a part replica of wc command in linux. It counts the number of lines, words and characters in a file.
$ go run main.go <filename>Also, supports reading from standard input if no file is provided to read.
$ cat abcd | go run main.go-l: Prints the number of lines in the file.-w: Prints the number of words in the file.-c: Prints the number of bytes in the file.-m: Prints the number of characters in a file. If the current locale does not support multibyte characters this will match the -c option
If no flag is provided, number of lines, words, and bytes are printed.
