Control: tags -1 + patch Um. idk if I tested this on something that just doesn't fail but yeah, retesting on my palmtop now, I repro your result. The correct spelling is read -r ONLINE 2>/dev/null < "./$x/online" || ONLINE= (and likewise for all the other variables) to void the errors /before/ trying to open the file, and clear on ENOENT, like the cats do.
Reverting 2e7b352c7bac543702d221736ed251f0ecadbb68 won't have any ill effect (-a -> ] && [ is a cosmetic change for all real shells), so either doing that or applying the attached patch should be equivalent. Best,
