No. Because udev (or whatever it is, perhaps libusb or kernel?) is somewhat broken by design because it assigns different device nodes to same devices (there are whatever technical reasons for this). Therefore your script must work with changing SANE devices. scanimage -f '%d,' lists the currently available SANE devices (see "man scanimage") so that you could use command substitution for example like scanimage -d $( scanimage -f '%d,' | tr ',' '\n' | grep hp2400 ) \ --format=tiff > Desktop/image.tiff The bash is needed for the nice $(...) command substitution syntax. Otherwise use your appropriate shell syntax for command substitution or the old-style backquote/backtick (accent grave) form in bash which could be confused with other kind of accent characters.
