GitHub can return release body with unescaped control characters (e.g. from
generated release notes); jq rejects them. Sanitize response in fetch_release
and list_releases before piping to jq (keep \n and \r).
- Use set +e around env/grep/read so grep (no match), read (EOF), and
[ -f ]/[ -s ] do not exit the script when no DNSMASQ_WEBUI_* or --set
- Write env vars to temp file .env then read; only process when file
exists and is non-empty
- Add || true after [ -s CONFIG_SET_FILE ] && cat so empty CONFIG_SET_FILE
does not trigger exit
Fixes install/update with no config (e.g. plain --version/--update --dir)
failing silently under sh (dash).
- Echo 'Installing dnsmasq-webui...' at start of do_install so output is visible
- Use </dev/null on all curl calls so they do not consume stdin; when run
as 'curl | sh' the script was being eaten and exited before any echo
- Add --set KEY=VALUE and env vars DNSMASQ_WEBUI_* to configure app at install
- Write env file for systemd (system: /etc/default/dnsmasq-webui; user: install-dir/dnsmasq-webui.env)
- Default ASPNETCORE_URLS=http://0.0.0.0:8080 so service listens on 8080
- Preserve existing env file on update (only overwrite when new config or first install)
- README: configure-at-install section, --set in options table, update preserves env note
- README: use master branch in raw GitHub URL (repo default branch)
- install.sh: trim repo and asset URLs (fix malformed URL when script has CRLF or trailing whitespace)
