debsecan:tldr:4ce4f
This command performs a system upgrade using the apt
package manager. It utilizes the sudo
command to execute the upgrade with administrative privileges.
The main part of the command $(debsecan --only-fixed --format ${packages})
involves the debsecan
tool, which checks for security updates specific to installed Debian packages. It is executed within $()
to capture its output and use it as an input for the apt upgrade
command.
The --only-fixed
flag ensures that only packages with available fixes for known vulnerabilities are considered. The --format ${packages}
option specifies the desired output format, which is the package names.
Therefore, the debsecan
command is responsible for listing the package names that need security fixes. This list is then passed as an argument to apt upgrade
, instructing it to update only those packages with available security fixes rather than upgrading all packages on the system.
