Hi, as noted just above this post, I find an error when executing this script. Any idea who the author is to whom I could report this error?
OH, yes I installed something called ‘sqlite3’ via Synaptic (no mention of the ‘binary’ bit though). I assume everything required is now there, because the error looks like it is within the script.
Hah! this worked just fine, allowing me to purge a few hundred ‘lost’ images very quickly. Strangely my technique of invoking ‘sh purge_non_existing_images.sh’ creates the script error previously mentioned.
Thanks for your advice. Minor hill of ignorance ascended.

sh is usually not the same as bash, which this script assumes. Probably it would have worked with bash purge_non_existing_images.sh.
Not strange, the script requires features specific to the bash shell, but when you invoke a shell using sh you only get a subset of bash shell features, in order to maintain compatibility with the original bourne shell. This is why you were seeing the error – the script was trying to use bash features not available within the sh subset. If you put bash purge_non_existing_images.sh, it should work, or alternatively if execute permission if set of the file, and invoke the execution of the file with ./purge_non_existing_images.sh, the #! line at the start of the file will cause the file to be run with bash shell.
OK, thanks for this explanation: I got into this situation through not understanding enough about the implications of the differences between 'sh; and ‘bash’ - probably because i never really had to use, or learn (not the same thing) any form of what I generally call ‘Unix’, including iOS.
Script runs fine, as you say.
