Learn to inspect the start of files quickly and effectively using the head command. 21.03.2026 | reading time: 2 min When a log or output file becomes long, use `head` to inspect the beginning fast and avoid scrolling; this guide shows concrete examples and work patterns to make the command useful right away. Live Example ```bash\n$ seq 1 11 | sed 's/.*/Line &/' | head -n 5\nLine 1\nLine 2\nLine 3\nLine 4\nLine 5\n``` Options That Matter Use `-n` to select a number of lines and `-c` to select a number of bytes, add `-q` to suppress headers when reading multiple files or `-v` to always show filenames; run `--help` for a quick local summary. Combine in Pipelines Pipe `head` into other tools to limit work: run `sort | head` to get top entries, or put `head` before expensive searches to reduce data scanned; for live files prefer `tail -f` combined with `head` via process substitution when you need the initial chunk. When It Won't Help Head reads raw bytes or lines but cannot peek inside compressed archives directly, so decompress or use zcat/gzcat before piping; also remember head only shows the start and is not a substitute for tools that extract context anywhere in a file. Final Steps Mastering `head` is a small win toward efficient file handling; practice on real logs, extend patterns with sed and awk and consider certification paths such as CompTIA Linux+ or LPIC-1 for structured skills, with bitsandbytes.academy offering intensive exam preparation.
