Examples for the tcpdump and dig man pages — by Julia Evans

A tour of what makes man pages easy to use: rsync's terse synopsis with a one-line option summary, strace's categorised options, curl's per-option examples, and the value of examples and tables of contents.

A portal of monitoring tools grouped by purpose; notably points to journalctl -b for current-boot logs and systemd-analyze (time, blame, critical-chain) for boot timing.

A curated list of newer command-line tools gathered from suggestions, grouped as modern replacements for standard utilities, tools that work differently, and JSON/CSV/grep-style helpers. Mentions ripgrep, fd, fzf, bat, direnv, jq and vidir.
