comment replace a 'space' char in filename with an underscore
This looks like the safest, most portable approach to me. Magic syntax stuff is always a little sketchy and hard for someone else to understand what's going on; this answer uses one of the 2 obvious choices for "character substitution" -- the other being tr IE var=$(echo "$var" | tr ' ' _)

So this is way off in the weeds but you need to quote both "$1" and "${i// /_}". Also, that ${var///} stuff looks like a non-posix shell extension (bash perhaps)?

Router A talks to Router B over the 192.168.250.1/30 subnet (A=192.168.250.1 and B=192.168.250.2)

comment What happens if I delete lost+found
It isn't that they couldn't create the lost+found -- it is that it is a bad idea to create files / directories on a filesystem that's already screwed up. Instead, you just prebuild a directory that's already big enough to store the directory entries of whatever munched inodes you find in a screwed-up filesystem when you're trying to clean it up.

comment Recursive move utility on Unix?
cp is terrible at this sort of thing because it typically destroys hard links / soft links and replaces them with individual files. Similarly it can't be trusted to keep ACLs straight and sometimes gets confused about sparse files.
