■概要
障害解析のためのログの調査、非互換対応でのソースコードの調査といった
テキスト処理で使った Perl ワンライナーのサンプル集です。
Perl ワンライナーは以下の点が良いと思います。
・Perl は Oracle Database (10g以降) に同梱されている。
 従って、Windows プラットフォームでも使える。

PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some 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)
