# WordCount Command Line Tool
This is simply an exercise from Build Your Own wc Tool from
[coding challenges website](https://codingchallenges.fyi/challenges/challenge-wc/)
## Description
This is my implementation in rust of the challenge build your own version of the Unix command line tool wc!
The Unix command line tools are a great metaphor for good software engineering and they follow the Unix Philosophies of:
- Writing simple parts connected by clean interfaces - each tool does just one thing and provides a simple CLI
that handles text input from either files or file streams.
- Design programs to be connected to other programs - each tool can be easily connected to other tools to create
incredibly powerful compositions.
Following these philosophies has made the simple unix command line tools some of the most widely used software
engineering tools - allowing us to create very complex text data processing pipelines from simple command line tools.
You can read more about the Unix Philosophy in the excellent book
[The Art of Unix Programming](http://www.catb.org/~esr/writings/taoup/html/).
## Quickstart
```console
$ cargo build -r
```
## Usage
- ./target/release/ccwc -flag filename
- flag is one of the following:
- c : for number of bytes in the file
- l : for number of lines in the file
- w : for number of words in the file
- m : for number of characters in the file
- h : print the help message
- if no flag is provided then it is equivalent to passing the default option - i.e. no options
are provided, which is the equivalent to the -l, -w and -c options.
- support being able to read from standard input if no filename is specified
## Example
```console
$ cargo run -- -c test.txt
$ 342190 test.txt
$ ./target/release/ccwc -c test.txt
$ 342190 test.txt
$ cargo run -- test.txt
$ 7145 58164 342190 test.txt
$ ./target/release/ccwc test.txt
$ 7145 58164 342190 test.txt
$ cat test.txt | ./target/release/ccwc -l
$ 7145
```
