fix(install): shell-safe one-liner (curl | bash)#64
Merged
Conversation
…rl …) `bash <(curl …)` uses bash process substitution, which /bin/sh (dash — the default on Debian/Ubuntu) can't parse: it errors "Syntax error: \"(\" unexpected" before anything downloads. Switch all install snippets to `curl -fsSL tracebloc.io/i.sh | bash`, which works from any shell and is the form the installer already supports (it reads prompts from /dev/tty). Variants handled: env-var prefixes move after the pipe (… | VAR=x bash) and args use `bash -s -- --diagnose`. 7 pages: quickstart, deploy-local, configuration, setup-guide, troubleshooting, prepare-dataset, overview.
