Common Command Line Options

The Pyrseas utilities support the following command line options:

-H host, ---host= host

Specifies the host name of the machine on which the PostgreSQL server is running. The default host name is 'localhost'.

-h, ---help

Show help about the program's command line arguments, and exit.

-o file, ---output= file

Send output to the specified file. If this is omitted, the standard output is used.

-p port, ---port= port

Specifies the TCP port on which the PostgreSQL server is listening for connections. The default port number is 5432.

-U username, ---user= username

User name to connect as. The default user name is provided by the environment variable :envvar:`USER`.

---version

Print the program version and exit.

-W, ---password

Force the program to prompt for a password before connecting to a database. If this option is not specified and password authentication is required, the program will resort to libpq defaults, i.e., password file or PGPASSWORD environment variable.

Short options (those only one character long) can be concatenated with their value arguments, e.g.:

dbtoyaml -p5433 dbname

Several short options can be joined together, using only a single - prefix, as long as only the last option (or none of them) requires a value.

Long options (those with names longer than a single-character) can be separated from their arguments by a '=' or passed as two separate arguments. For example:

dbtoyaml --port=5433 dbname

or:

dbtoyaml --port 5433 dbname

Long options can be abbreviated as long as the abbreviation is unambiguous:

dbtoyaml --pass dbname
