Synology - Rescan with command line

[lyapounov]

Hello

I must be blind or tired, but I don't figure how I can launch a rescan on my synology using command line ?

I am stuck here : http://minimserver.com/ug-control.html#C...20commands

If I understand, I have to type
<minimserverdirectory>/minimserver/bin/rescan

But I don't know where is the minimserver directory on my synology ? I could not figure it out.

Thx for help !
Best
