I occasionally do "ls -laR /" on my system and offsite backup the results. If disaster strikes, I'll at least know which files I've lost.
I recently started sshfs mounting remote systems, yielding two problems:
"ls -laR" on sshfs mounted systems is painfully slow
I don't need the "ls -laR" results of remote filesystems, at least not locally.
What's the ls equivalent of find's "-xdev" option or du's "-x" option?
In case there's a better way to do it, my goal is to efficiently get a list of all files on my hard drive with size, owner, mod time, etc. In other words, all the info "ls -l" would normally provide.
I've considered: "find / -xdev | xargs ls -la", but I sense that would be less efficient.
There is no such option for ls itself, but you can do
find / -xdev -ls
or if that is not sufficiently detailed, look into the possibilities offered by the -printf option.
