4.1.3. Installing syslog-ng without user-interaction

The syslog-ng application can be installed in silent mode without any user-interaction by specifying the required parameters from the command line. Answers to every question of the installer can be set in advance using command-line parameters.

./syslog-ng-premium-edition-<version>.run -- [options]

	Warning
	The `--` characters between the executable and the parameters are mandatory, like in the following example: `./syslog-ng-premium-edition-3.0.1b-solaris-10-sparc-client.run -- --accept-eula -l /var/tmp/license.txt`

To display the list of parameters, execute the ./syslog-ng-premium-edition-<version>.run -- --h command. Currently the following options are available:

--accept-eula or -a: Accept the EULA.
--license-file <file> or -l <file>: Path to the license file.
