  --total          Show grand total (default with multiple files)
  --json          Output as structured JSON

Examples

bash

# Full count (lines, words, chars, bytes)
wc-tool README.md

# Lines only (code file size metric)
wc-tool -l src/main.py src/utils.py

# Characters in a file (UTF-8 aware)
wc-tool -m document.txt

# Longest line length
wc-tool -L src/main.py

# Pipe from another command
ls /usr/bin | wc-tool -l

# JSON output for automation
wc-tool -l -w *.py --json

# Multiple files with total
wc-tool *.txt
