AVG Linux Email Server / User Manual

Optional update

The optional update reflects changes that are not necessary for program

functionality – texts, updates of the setup component, etc. Optional updates

can be downloaded and applied together with recommended updates but the

timeliness of implementing them is not urgent.

Note: For e-mail servers in general it is strictly recommended to perform the

priority update approximately every two hours! The recommended update should be

performed at least once a day or on-demand.

You can review the performed update information in the update log file

avg7upd.log that is to be found in the

/opt/grisoft/avg7/var/update/log

directory.

The

avgupdate command is a tool for complex control over the on-demand update

process. The update in general can be performed by launching this command. The

update properties are controlled using the command options, which are listed in the

table below. General syntax of the command is:

$ avgupdate [options] [path|list]

The

[path|list] string stands for the path of the explicitly given update files (or for

the list of these update files separated by the space character).

Note: Although the avgupdate command itself can manage only the on-demand

update, you can also use it to create scheduled updates by incorporating the

cron

Linux system utility. See the manual pages (man [cron|crontab]) or the respective

documentation for detailed information.
