I typically develop sites on my local machine using custom vhosts in Apache and adding lines to my
/etc/hosts file to point custom urls to
127.0.0.1. After some time that file grew to be large and sometimes tedious to update. Enter ghost gem. Simple hostname management.
1 Waffles:~ clint$ ghost modify pup.local 127.0.0.1 2 [Modifying] pup.local -> 127.0.0.1
Adds a new entry (somewhere, not /etc/hosts though) and you can now use puppy.local as a url to point to your machine with a vhost setup to respond to that scheme.
You can use this for just about any url or IP you want too:
1 Waffles:~ clint$ ghost add puppy google.com 2 [Adding] puppy -> 126.96.36.199
ghost list shows what you have already:
1 Waffles:~ clint$ ghost list 2 Listing 2 host(s): 3 pup.local -> 127.0.0.1 4 puppy -> 188.8.131.52
