[sane-devel] scanbd with Fujitsu fi-7260 Scanner: need help

[Dirk Meier]

Hello,
I would finally like to use the buttons on my Fujitsu fi-7260 scanner. I have 
found the program scanbd for this purpose.
The scanner has a selector switch for 10 positions, from 0 to 9. The positions 
are transferred numerically. I checked this with scanimage -A:
~>sudo scanimage -A
[sudo] Passwort für root: 
Output format is not set, using pnm as a default.
...
--function <int> [2] [hardware]
        Function character on screen
...

With:
sudo scanbd -f -d7 the transfer to scanbd is also recognizable 
(SCANBD_FUNCTION=2):
~> sudo scandb -f -d7 > tmp.txt
...
scanbd: trigger action for email for device fujitsu:fi-7280:1201263 with script

I have tried the following filters: “2”, “.*2.*”, “^2.*”, “.*2$” none of them 
worked. Only when I use “.*” as a filter is the assigned script executed. But 
continuously.

I don't know how the string to be filtered is actually structured, nor how I 
can find out.
Scanbd version 1.5.1-lp155.3.1 is running on a Leap 15.5.
Can anyone help?
