This script displays partitions (volumes) properties, including device names, mount status, filesystem, label, uuid and - when used with the --verbose option - partitions start sector and size. The point is not to gather informations about partitions - as fdisk and blkid would be faster and more appropriate for that purpose - but to get these informations from Hardware Abstraction Layer as they are passed to the applications (like the dolphin filemanager among others) through the message bus.
Usage: halinfo [ -c | --color ] [ -v | --verbose ]
The --color option produced a two colors output (might be easier to read if you have a lot of partitions). Since escape sequences get lost by copying/pasting, I removed them from the code before posting. A compressed version of the script with preserved escape sequences is available here: http://www.unixversal.com/linux/openSUSE/halinfo.gz.
The --verbose options displays two more columns: the partitions start sector (in sector - 512 or 4096 byte according to the value of volume.block_size property) and the size in MB, rather than sectors (as it would get too confusing on system with hard disks of different sector size). Both values are originally written in byte in the hal properties.

#: Description : displays hal volume (partitions) properties
# using volume_uuid for Linux and DOS partitions and volume_part for others (like ufs)
#: usage : halinfo
#: options: -v --verbose : verbose output (display offset and size of the partitions)
# -c --color : more readable colored ouput
#
# Copy and paste this text into a text file and save it in your home area, bin folder (~/bin) as the file halinfo
# Once the file is saved, you must make the file executable using the terminal command: chmod +u ~/bin/halinfo

Screenshot of a system with many partitions:
You can ignore or remove the text in gray. I didn’t want to write/maintain several scripts for my different linux distros.
