im using ubuntu on my server.
when I want to move some old files, I get using this command find . -maxdepth 1 -mtime +900 -exec mv "{}" ../backup ;
to move my old files but accidentally miss the slash char at the end of the target which i should type ../backup/
. now my files are gone, vanished, just only left one file named backup. anyone can help me to recover my files?
