How to delete the history and cache in Opera Mobile (10.1) via shell?

I run **Opera Mobile 10.1** on Android. My device is rooted. **How can I clear the history and cache of the browser via shell?** As su, removing > /data/data/com.opera.browser/opera/profiles/smartphone/cookies4.dat > > /data/data/com.opera.browser/opera/profiles/smartphone/cache > > /data/data/com.opera.browser/opera/profiles/smartphone/cacheO and a > /system/xbin/busybox killall -9 > com.opera.browser afterwards doesn't seem to do the job. Afterwards, bookmarks etc. are still there. In **Opera Mini** I found it easy to just delete > /data/data/com.opera.mini.android/cache/webviewCache > > /data/data/com.opera.mini.android/databases but unfortunately, Opera Mini in it's current version has a bug and doesn't work on most devices. **Edit:** Another approach I tried is to kill the Opera process, then set an entry in the **opera.ini**, referring to http://www.opera.com/support/usingopera/operaini/#private : [Clear Private Data Dialog] CheckFlags=1023 but it doesn't cause Opera to clear the history and cache after a restart.
