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#

bash

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#

bash

# 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
