  • The above command assumes the lost data is on /dev/sda and you previously issued the following command to mount _another_ disk or partition (/dev/sdb1) on /recovery sudo mount /dev/sdb1 /recovery If you don't do this, the data could be overwrited! foremost is a very powerful carving tool. By default foremost recovers all known file types. If you want to reduce the amount of files that are recovered you can specify the file type you are looking for. Read the man page to know the available file types. i.e to recover JPEG pictures append to foremost the switch -tjpg

    sudo foremost -i /dev/sda -o /recovery

  • Necessary for fsck for example. The remount functionality follows the standard way how the mount command works with options from fstab. It means the mount command doesn't read fstab (or mtab) only when a device and dir are fully specified. After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command. It does not change device or mount point.
