May 19, 2015 - A Look At The New Commandlinefu
I've put together a short writeup on what kind of newness you can expect from the next iteration of clfu. Check it out here.
March 2, 2015 - New Management
I'm Jon, I'll be maintaining and improving clfu. Thanks to David for building such a great resource!

Show the UUID-based alternate device names of ZEVO-related partitions on Darwin/OS X. Adapted from the lines by dbrady at http://zevo.getgreenbytes.com/forum/viewtopic.php?p=700#p700 and following the disk device naming scheme at http://zevo.getgreenbytes.com/wiki/pmwiki.php?n=Site.DiskDeviceNames

Shows all block devices in a tree with descruptions of what they are.

User: mhs

`blkid` is an interface to libuuid - it can read Device Mapper, EVMS, LVM, MD, and regular block devices.

-c /dev/null - Do not use cached output from /etc/blkid.tab or /etc/blkid/blkid.tab (RHEL)

-i - Display I/O Limits (aka I/O topology) information (not available in RHEL)

-p - Low-level superblock probing mode (not available in RHEL)

See size of partitions as human readable and get extra informations about hdd and partitions

fdisk -l /dev/sda | grep -E sda[0-9]+ | sed s/*// | awk '{printf ("%s %f ",$1,$2/512); if($2%512){ print "BAD" }else {print "Good"} }' | column -t

To get most of you HDD/SSD driver you need to make sure you partition are aligned, if not the speed penalty can be up to 50% slower!

this simple one liner will check to see if each partition start sector is divided by 512

you need to change sda with your driver

if you find the one of your partitions is not aligned use gparted to move the start sector of the partition to be divided of 512

echo "0,,L" | sfdisk /dev/sdX

User: twobitsprite
Functions: echo

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

losetup /dev/loop0 harddrive.img; kpartx -a -v /dev/loop0; mount /dev/mapper/loop0p1 /mountpoint/
mount -o remount,ro /dev/foo /
2010-10-30 03:51:53
User: vlan7
Functions: mount

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.

blkid /dev/sda7
2010-09-05 12:20:45
User: lineak
Tags: partition uuid

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

sudo foremost -i /dev/sda -o /recovery
2010-08-19 22:27:41
User: vlan7
Functions: sudo

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

df -l | grep -e "9.%" -e "100%"

User: dooblem
Functions: df grep

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)

sfdisk -d /dev/sda | sfdisk /dev/sdb
sfdisk -d /dev/sda | sed 's/sda/sdb/g' | sfdisk /dev/sdb
sfdisk /dev/sdb <(sfdisk -d /dev/sda| perl -pi -e 's/sda/sdb/g')
2009-12-22 22:45:41
Functions: perl

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

lomount -diskimage /path/to/your/backup.img -partition 1 /mnt/foo

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.

hwinfo --block --short
2009-04-24 11:13:31

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.

INFILE=/path/to/your/backup.img; MOUNTPT=/mnt/foo; PARTITION=1; mount "$INFILE" "$MOUNTPT" -o loop,offset=$[ `/sbin/sfdisk -d "$INFILE" | grep "start=" | head -n $PARTITION | tail -n1 | sed 's/.*start=[ ]*//' | sed 's/,.*//'` * 512 ]

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).
