||
Actions
|
||
deleteinstswhere <condition[s]>

|
||
them in other tables.
|
||
Example: mustool.php deleteinstswhere "Dead=1"
|
||
shuffle
|
||
Randomizes instances list (values in «RPos» column).
|
||
updstats
|
||
Updates site’s statistics.
|
||
clean
|
||
Deletes records older than '.$opts['clean_before_weeks'].' weeks from
|
||
«Notifications» table.
|
||
resurrect
|
||
Sets «Dead=0» on all «Instances» records.
|
||
optimize
|
||
Optimizes all the tables in the database.
|
||
OPTIONS
|
||
-h, --help
|
||
