psql
Description
psql is a terminal-based front-end to PostgreSQL. It enables you to type in queries interactively, issue them to PostgreSQL, and see the query results. Alternatively, input can be from a file. In addition, it provides a number of meta-commands and various shell-like features to facilitate writing scripts and automating a wide variety of tasks.
- -c command
--command command - PostgreSQL 7.2 devel Documentation
Specifies that psql is to execute one command string, command, and then exit. This is useful in shell scripts.
command must be either a command string that is completely parsable by the server (i.e., it contains no psql specific features), or it is a single backslash command. Thus you cannot mix SQL and psql meta-commands. To achieve that, you could pipe the string into psql, like this: echo "\x \\ select * from foo;" | psql.
If "autocommit" is on, multiple queries in a single string are processed in a single transaction.
