Short Order Ruby
summary
Concrete recipes for command-line Ruby: one‑liners with -n -e -i edit files in place, use $_ and ARGF to process streamed or filename input, and set IO.sync = true to avoid buffering. Show subprocess patterns: backticks/%x, popen/popen3 and PTY plus select for multiplexing and expect for prompts. Built examples include a Campfire multiplayer text‑adventure bridge that works, a MySQL pager that draws Unicode bar charts, and a reusable header-insert script used three times.
