This is equivalent to specifying dbname as the first non-option argument on the command line. << ...and... I want to run "select name from table_a where name like 'john%'" >> -c command --command command 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 a single backslash command. Thus you cannot mix SQL and psql meta-commands with this option. To achieve that, you could pipe the string into psql, like this: echo '\x \\ SELECT * FROM foo;' | psql. (\\ is the separator meta-command.) If the command string contains multiple SQL commands, they are processed in a single transaction, unless there are explicit BEGIN/COMMIT commands included in the string to divide it into multiple transactions. This is different from the behavior when the same string is fed to psql's standard input. << ...and... I want no table header "NAME" in the output >> -t --tuples-only Turn off printing of column names and result row count footers, etc. This is equivalent to the \t command. << ...and... I want to do this as a one-liner from the linux command line ...and... I don't want to have to deal with intermediate files or home-grown programs... Is this possible? >> Read The Fine Manual. <<
