RWC - Ruby WC Tool

wc (word count) is a command-line tool in Linux used to gather various statistics from a given file or input stream. These statistics include the number of lines, word count, character count, and byte count in the specified file. rwc is a similar tool built using Ruby, offering the same features and the ability to accept input from the standard input stream.

Setup

1. Ensure you have Ruby installed on your system.
2. Navigate to the ruby directory containing the source code.
3. Install the necessary dependencies using bundle install.
4. You're all set to explore this versatile tool!

Usage

Run bin/rwc with the following options:

• -l: Print the number of lines in the file.
• -w: Print the number of words in the file.
• -c: Print the number of bytes in the file.
• -m: Print the number of characters in the file.

Examples

1. For a file named test.txt, when no option is provided, rwc displays line count, word count, and character count:

   foo:~$ bin/rwc test.txt
   7143 58164 334997 test.txt

2. To count the number of lines in test.txt:

   foo:~$ bin/rwc -l test.txt
   7143 test.txt

3. Input from standard input stream using a pipe (|):

   foo:~$ cat test.txt | bin/rwc
   7143 58164 334997

4. Input from standard input strea

   foo:~$ bin/rwc
   hello world
   A sample line
   2 5 26

5. Input from standard input strea with option (-w)

   foo:~$ bin/rwc -w
   hello world
   A sample line
   5

Test

Run the tests using the rake command

rake test
