File Header Viewer

Output the beginning of files, defaulting to the first 10 lines. Essential for previewing log files, CSV headers, and large text files without loading them entirely.

Usage

head-tool [options] [file...]

Options

• -n N: Show first N lines (default: 10)
• -c N: Show first N bytes instead of lines
• -q: Quiet mode (suppress filename headers)
• Read from stdin when no file specified

Examples

# Show first 10 lines
head-tool data.csv

# Show first 20 lines
head-tool -n 20 log.txt

# Show first 100 bytes
head-tool -c 100 config.yaml
