## DESCRIPTION

db.login sets the user name and optionally also a password for the connection to the selected database through the DB driver.

## NOTE

This is only related to SQL database backends like PostgreSQL, MySQL or ODBC. The passwords are stored in a hidden unencrypted file in the user account ('home' directory) called .grasslogin64. Only the file owner can access this file.

## EXAMPLES

Only username specified (password will be interactively queried to remain invisible):

    db.login user=bacava

Username and password specified (note that the command lines history will store the password in this way):

    db.login user=bacava password=secret

Username and empty password specified (note that the command lines history will store the password in this way):

    db.login user=bacava password=""
