Who the fdisk?

|

Found another cool time saver tip. For me I find myself looking for partition mount points. So I usually do:

fdisk /dev/hda

The number of cylinders for this disk is set to 4982.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/hda: 40.9 GB, 40982151168 bytes
255 heads, 63 sectors/track, 4982 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          13      104391   83  Linux
/dev/hda2              14         523     4096575   83  Linux
/dev/hda3             524         778     2048287+  83  Linux
/dev/hda4             779        4982    33768630    5  Extended
/dev/hda5             779         909     1052226   82  Linux swap
/dev/hda6             910        4982    32716341   8e  Linux LVM

I would do this for all drives, or if I didn't know what device, I could run through the alphabet. Most recently I was searching for a USB thumb drive I just plugged in. So here is my time saver tip just learned today:

fdisk -l

Looky looky, all my drives that make up my boxtop backup server. Will have to post the pic of that here soon.

Amazing what use 'man' is..

-l List the partition tables for the specified devices and then exit. If no devices are given, those mentioned in /proc/partitions (if that exists) are used.
