Bash shortcuts to run Rails commands through Spring, Bundler, or ye olde scripts

0

Just about a year ago to date I posted some useful Bash shortcuts for Ruby on Rails commands. These are mix of aliases and functions that detect what version of Rails is present and routes commands which ever way that version expects, i.e. ./script/console versus rails console. Now that Rails 4.1 ships with Spring by default, there is yet one more way commands could be routed – through the spring binstubs. I’ve recently updated my shortcuts to account for this. Now my commands will use the binstubs if they are present, or fallback to the other version-dependent methods.

H/T to makandracards for helping me figure this out.

Read an updated article on my Rails shortcuts: Bash shortcuts to run Rails commands through Spring, Bundler, or ye olde scripts

Like any developer, I spend a lot of time in the terminal typing out commands. Anything I can do to cut down on keystrokes is a daily win, which is why I’ve got over 50 bash alias entries.

I frequently have to work on a several different Rails projects at a time, ranging in versions from 2.3 – 4.0. Hammering out commands for console, server or generate can get pretty tedious by the end of the day, so I came up with a couple shortcuts that I’m particularly fond of:

What I like most about the cons, srv and gen commands is that they eliminate the mental overhead of context switching when going from the old 1.x and 2.x projects where each command is a separate bin file versus the newer 3.x+ project where they are just arguments to the rails command – It’s the same alias for every project.

Using dig to view, backup and verify DNS zone records on OS X

I was recently asked by a client to consolidate all of their DNS zone records and domain name registrations from 2 separate services to a single provider. The FAQ page of the current DNS service recommended using the named-xfer shell command, but that utility isn’t available on OS X. I googled around and learned that dig is a suitable alternative.

Finding the nameservers

Dig can be used to find nameserver information for a given domain:

Viewing and Backing up DNS Records

Backing these up just requires you to send that output to a file: dig @ns1.nameserver.com yourdomain.com IN ANY >> dns-backup-yourdomain.com-ns1.nameserver.com

Once you’ve updated the nameservers for a domain you can verify if they’ve changed using the dig yourdomain.com NS +short command.
