Well my transfers aren't "time critical" either, but life feels easier if I don't have to jump through hoops to solve a task that involves copy files around.
Re: next cloud, looking for something more lightweight than that.
Honestly, if a script grows to more than a few tens of lines I'm off to a different scripting language because I've written enough shell script to know that it's hard to get right.
Shellcheck is great, but what's greater is a language that doesn't have as many gotchas from the get go.
Too much typing, especially if transferring from phone to computer.
Thanks though.
