Commands tagged partition

Creates a single primary partition starting at sector 0 and extending to the end of the disk. Use with care.

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.

Shows the UUID of the given partition (here /dev/sda7). Doesn't need to be root.

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

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

Reports all local partitions having more than 90% usage.

Just add it in a crontab and you'll get a mail when a disk is full.

(sending mail to the root user must work for that)

*as long as the drives are exactly the same* then this command copies the partition table on /dev/sda to /dev/sdb

Instead of calculating the offset and providing an offset option to mount, let lomount do the job for you by just providing the partition number you would like to loop mount.

Yields entries in the form of "/dev/hda1" etc.

Use this if you are on a new system and don't know how the storage hardware (ide, sata, scsi, usb - with ever changing descriptors) is connected and which partitions are available.

Far better than using "fdisk -l" on guessed device descriptors.

Suppose you made a backup of your hard disk with dd:

dd if=/dev/sda of=/mnt/disk/backup.img

This command enables you to mount a partition from inside this image, so you can access your files directly.

Substitute PARTITION=1 with the number of the partition you want to mount (returned from sfdisk -d yourfile.img).
