While running Linux, if you want to list the contents of a folder in a vertical list format, just use the ls command with these switches.

ls -hula --color=auto

then you get the directory listing with human readable file sizes instead of being listed in bytes.

To list the partitions on a disk, just type this command.

fdisk -l /dev/sdb

for example and it will list the partitions on the device. You need superuser priviledges to run this command. Then you get the output below.

linux-3d5u:/home/shoggoth # fdisk -l /dev/sdb
 
Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000bd059
 
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1        7858    63118336   83  Linux
/dev/sdb2            7859       19457    93168937    5  Extended
/dev/sdb5            7859       15580    62026933+  83  Linux
/dev/sdb6           15581       17228    13237528+  83  Linux
/dev/sdb7           17229       19083    14900256   83  Linux
/dev/sdb8           19084       19457     3004123+  82  Linux swap / Solaris

A very useful command. This is useful when I am double checking which partition to install Linux to on my hard drive so I do not overwrite the wrong partition.
