How to reload the explorer-3.db

ZackMuc · 02-26-2025, 08:56 AM

I manage my collections for my books with the Pocketbook collection manager. This generally works, but sometimes the explorer-3.db is corrupt and after disconnection from my PC or restarting the Pocketbook .. all books are marked as new and all collections are empty. My solution until now is to have a backup on my pc and replace it.

What is want to do now to be independent of my pc. I have a script backup which copies this db to a seperate folder .. and an script restore to overwrite the used db with the backup. The probelm is after the restore the new db is not used and if i reboot and check the db a new one is created. When i do the manual way (copying from my pc) and disconnect it from pc i see the wheel which seems the reload of the db, and it works .. how can i manually force such a reload?

Regards

Peter

You can try calling the scanner app, I think I had luck using it in a script where I wanted database changes to show immediately.

/ebrmain/cramfs/bin/scanner.app

If I remember it right you have to kill scanner.app and restart it (scanner.app) afterwards.

Try this:

Code:

 /ebrmain/cramfs/bin/scanner.app & sleep 3; kill "$!"

Can you tell me how to do?

nhedgehog · 03-04-2025, 07:02 AM

Not sure about this but I think years ago I did it with:
pkill -HUP explorer.app

ZackMuc · 03-04-2025, 07:57 AM

did not reload the db

nhedgehog · 03-04-2025, 08:01 AM

Maybe you should restart the scanner app after killing it:
/ebrmain/cramfs/bin/scanner.app & sleep 3; kill "$!"
sleep 3
/ebrmain/cramfs/bin/scanner.app

do i have to do the last command with &? the screen stays white now

nhedgehog · 03-04-2025, 08:28 AM

sounds like you have to kill scanner app. Try the code neil_swann80 gave you but with a different sleep time:
/ebrmain/cramfs/bin/scanner.app & sleep 15; kill "$!"

ZackMuc · 03-06-2025, 04:00 AM

Somehow it does not work

Just had a look at an old script I used.

pkill -HUP explorer.app

did the trick for me as I wrote before. But scrolling through the conversation here again does make me wonder, why the heck didn't you provide more infos on your device?
