Environment variables and GNATS tools

All the GNATS user tools honor the GNATSDB environment variable which is used to determine which database to use. For a local database, it contains the name of the database to access.

For network access via gnatsd, it contains a colon-separated list of strings that describe the remote database in the form


Any of the fields may be omitted except for server, but at least one colon must appear; otherwise, the value is assumed to be the name of a local database.

If GNATSDB is not set and no command-line options are used to specify the database, it is assumed that the database is local and that its name is default.
