But how i can make single (non automatic) deletion of all logs? Can it (deletion) be done manually (from cli)?
The answer is yes.
By default ZS keep current logs on
- Database – the mount point of _DB.001(user database)
- LOG – log directory
- 2011 -current year
- May – current month
- 30 – current day
A direct command to remove the logs for current day is
rm -R /Database/LOG/2011/May/30
Before you consider deleting the current logs you should backup(compressed) your logs.
tar cjf May30.tar.bz2 30
Just few basic examples, from here you can start learning about *nix basic commands and shell scripting for other options.
