I was building a floppy drive Linux distro for file recovery. I had it mounted under /mnt and wanted to do ‘rm -rf ./home’ inside /mnt but did ‘rm -rf /home’. I noticed quickly and hit Ctrl+C but still a lot of files were gone. Fortunately my file recovery distro was nearly finished so I’ve booted it and recovered all my files. I never had to use this distro again.
