Less

Paginate and search text files interactively

Prerequisite Check

Run this before choosing an interactive pager workflow:

command -v less >/dev/null 2>&1 || less --version

If less is missing, switch to non-interactive fallbacks such as head, tail, or sed -n, and note that search/navigation will be more limited.

Quick Start

1. Verify less is available: less --version or man less
2. Establish the command surface: man less or less --help
3. Start with basic usage: less [options] [input]
