ccwc - Word Count Clone

A simple clone of the Unix wc utility written in Go. Counts lines, words, characters and bytes in text files or standard input.

Features

• Counts lines (-l), words (-w), characters (-m), and bytes (-c)
• Handles multiple files
• Supports standard input through pipes
• Unicode-aware character counting
• Combines flags (e.g. -lwm)

Build

go build -o ccwc . 

Usage

ccwc [flags] [files...]

# Default behavior (-clw) on a file
ccwc file.txt

# Count only lines and words in multiple files  
ccwc -lw file1.txt file2.txt

# Count characters from standard input
cat file.txt | ccwc -m

# Count lines from standard input
echo "hello\nworld" | ccwc -l

Flags

• -l count lines
• -w count words
• -m count characters (Unicode support)
• -c count bytes

Multiple flags can be combined: -lwm
If no flags are specified, defaults to -clw

Examples with Output

$ echo "hello world" | ccwc
       1       2      12

$ ccwc -lw test.txt
    7145   58164 test.txt

$ ccwc -c README.md
     1271 README.md
