I was running through the most excellent Ruby on Rails Tutorial 7th Ed.<\/a> (by Michael Hartl) and wanted to launch the development web server. However, I mis-typed the command.<\/p>\n\n\n\n

“rails -s”<\/h2>\n\n\n\n

brianvagnini@Brians-Mac-mini-2 sample_app % rails -s<\/strong><\/p>\n\n\n\n

Running 2 tests in a single process (parallelization threshold is 50)<\/p>\n\n\n\n

Run options: –seed 49801<\/p>\n\n\n\n

# Running:<\/p>\n\n\n\n

..<\/p>\n\n\n\n

Finished in 0.391693s, 5.1060 runs\/s, 5.1060 assertions\/s.<\/p>\n\n\n\n

2 runs, 2 assertions, 0 failures, 0 errors, 0 skips<\/p>\n\n\n\n

<\/p>\n\n\n\n

Vs.<\/p>\n\n\n\n

“rails s” (Starts the development web server)<\/h2>\n\n\n\n

brianvagnini@Brians-Mac-mini-2 sample_app % rails s<\/strong><\/p>\n\n\n\n

=> Booting Puma<\/p>\n\n\n\n

=> Rails 7.0.7 application starting in development <\/p>\n\n\n\n

=> Run `bin\/rails server –help` for more startup options<\/p>\n\n\n\n

Puma starting in single mode…<\/p>\n\n\n\n

* Puma version: 5.6.6 (ruby 3.1.2-p20) (“Birdie’s Version”)<\/p>\n\n\n\n

*  Min threads: 5<\/p>\n\n\n\n

*  Max threads: 5<\/p>\n\n\n\n

*  Environment: development<\/p>\n\n\n\n

*          PID: 2099<\/p>\n\n\n\n

* Listening on http:\/\/127.0.0.1:3000<\/p>\n\n\n\n

* Listening on http:\/\/[::1]:3000<\/p>\n\n\n\n

Use Ctrl-C to stop<\/p>\n\n\n\n

<\/p>\n\n\n\n

So what does this mean?<\/h2>\n\n\n\n

Apparently , the “-s” option (per rails -help<\/strong> command) means <\/p>\n\n\n\n

”\u00a0 \u00a0 -s, –silent \u00a0 \u00a0 Like –quiet, but also suppresses the ‘in directory’ announcement.”<\/p>\n\n\n\n

”\u00a0\u00a0 -q, –quiet\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Do not log messages to standard output.”<\/p>\n\n\n\n

Running “rails” by itself yields:<\/p>\n\n\n\n

The most common rails commands are:<\/p>\n\n\n\n
