system-update - update a Debian system automatically

system-update [options ]

system-update will update a Debian system. The sources.list.security and sources.list.default APT package resource list files must be present (see below) and /etc/apt/sources.list must be a symbolic link. The default action is to use the sources in /etc/apt/sources.list.default after applying any updates from the /etc/apt/sources.list.security sources file. If the -s option is specified, the /etc/apt/sources.list.stable sources will be used instead of the default.

-S

Upgrade with security updates only (/etc/apt/sources.list.security must contain the appropriate sources).
