Audit Trail preview vs run on linux

I’m a little bit confused about using audittrail.

Running:

/opt/BESServer/bin/BESAdmin.sh -audittrailcleaner -olderthan=365 -preview

gives an output as expected with the cleanup actions. Trying to run:

/opt/BESServer/bin/BESAdmin.sh -audittrailcleaner -olderthan=365 -run

shows the usage.
Running against a single content eg. “oldcontent”:
/opt/BESServer/bin/BESAdmin.sh -audittrailcleaner -oldcontent -olderthan=180 -run
works fine ?

In addition, looking at documentation:
https://www.ibm.com/support/knowledgecenter/SSQL82_9.5.0/com.ibm.bigfix.doc/Platform/Installation/c_running_the_tivoli_endpoint_ma_onlinux.html#c_running_the_tivoli_endpoint_ma_onlinux

the default value for “olderthan” should be 99 days. Looking at output from

/opt/BESServer/bin/BESAdmin.sh -audittrailcleaner -displaysettings

it seems to be set to 180 Days:

/opt/BESServer/bin/BESAdmin.sh -audittrailcleaner -displaysettings
