Thanks for your response
tshering,
Yes, preset scripts do work perfectly, there's no issue with that.
The thing i'm trying to achieve is: script gets index -> extracts all the files from <a> tags -> downloads them and rewriting existing stuff in the folder.
Now about logging. I was wondering if that's possible to log things into some file 'cause i really want to write the script by myself (just to prove something to myself, and, of course, get the task done), could you possibly tell me how to do the logging?
About vlasovsoftlauncher. Thanks for pointing me to the ksmhome.sh, and yeah, i do understand that VSL doesn't start coolreader by default but i do have "autostart" options in VSL set to Coolreader, so in my case it actually does start Coolreader.
NiLuJe, thanks for advice, i'd definitely look into rsync, it seems even more fitting than wget for that task (if i'll find out how to use it on kobo lol)
Ken Maltby, i was thinking about OPDS stuff but unfortunately i don't use Koreader and Coolreader doesn't actually have an OPDS feature. So that's not my way to do things here. But thanks anyway
UPD: edited ksmhome, got rid of long line, got rid of that rocket icon, changed it to book, set autostart to 3+coolreader - user experience improved.
UPD2: found the kbterminal thing (why didn't i see it earlier? i think i was blind or tired. or even both.), gotta try to debug my script through this.
