This list is based on aliases_spec.rb.
You can see also Module: RSpec::Matchers API.
| matcher | aliased to | description |
|---|---|---|
| a_truthy_value | be_truthy | a truthy value |
| a_falsey_value | be_falsey | a falsey value |
| be_falsy | be_falsey | be falsy |
| a_falsy_value | be_falsey | a falsy value |
Magic words:
psql -U postgresSome interesting flags (to see all, use -h or --help depending on your psql version):
-E: will describe the underlaying queries of the \ commands (cool for learning!)-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
These are my notes basically. At first i created this gist just as a reminder for myself. But feel free to use this for your project as a starting point. If you have questions you can find me on twitter @thomasf https://twitter.com/thomasf This is how i used it on a Debian Wheezy testing (https://www.debian.org/releases/testing/)
