+====== showmydisks ======
+A [[http://www.gnu.org/software/bash/|Bash]] script to report partitions, types, file systems, and disk space usage
+===== Synopsis =====
+<code bash>
+showmydisks [-L] [-u] ["dev1 ... devN"]
+</code>
+===== Description =====
+''showmydisks'' tries to list all "disks", partitions, their types, and if available file systems, disk space usage, and mount points. Option ''-u'' also prints the number of unallocated sectors as reported by ''fdisk''. ''-L'' returns only the list of devices.
+The script has not been tested much but was known to run well on Debian 4 and 5 and Ubuntu 9 and 10.
+v0.12 has been tested on Debian 7.9 and Lubuntu 14.04.3.
+===== Examples =====
+<code>
+root@ubuntu:~# ./showmydisks
+> sda: ATA FUJITSU MHZ2160B (149 GB)
+|-- 1: type 7 (NTFS?) 9 GB on /windows as fuseblk (5 GB free)
+|-- 2: 188 MB on /boot as ext3 (142 MB free)
+|-- 3: extended partition
+|-- 5: Linux swap partition, 956 MB
+|-- 6: 956 MB on /tmp as ext3 (876 MB free)
+|-- 7: 1 GB on /var as ext3 (1 GB free)
+|-- 8: 760 MB on / (430 MB free)
+|-- 9: 4 GB on /usr as ext3 (1 GB free)
+|-- 10: type 7 (NTFS?) 116 GB on /data as fuseblk (86 GB free)
+> sdb: Kingston DataTraveler II (983 MB)
+|-- 1: partition type e
+> sdc: WD 10EAVS External (931 GB)
+|-- 1: type 7 (NTFS?) 931 GB vfat|msdos
+> sdd: WD 10EAVS External (931 GB)
+|-- 1: type 7 (NTFS?) 931 GB on /import/KRAM as fuseblk (649 GB free)
+</code>
+Show also number of unallocated sectors (''-u''), list only a specific disk:
+<code>
+root@ubuntu:~# ./showmydisks -u sdb
+> sdb: WD 10EAVS External (931 GB)
+|-- 1: type 7 (NTFS?) 931 GB vfat|msdos
+(5165 unallocated sectors)
+</code>
+Run as unprivileged user (non-root):
+<code>
+user@debian:~$ ./showmydisks
+showmydisks: warning: you probably want to be root
+> hda: IBM-DTTA-351680 (15 GB)
+|-- 1: type unknown 15 GB on /backups as ext2 (2 GB free)
+> sda: ICP Host Drive #00 (34 GB)
+|-- 1: type unknown 250 MB on / as ext2 (170 MB free)
+|-- 2: type unknown 23 MB on /boot as ext2 (13 MB free)
+|-- 3: type unknown 321 MB fs unknown
+|-- 4: type unknown 1 KB fs unknown
+|-- 5: type unknown 305 MB on /tmp as ext2 (275 MB free)
+[...]
+</code>
+The above example shows that as non-root user partition types are not read. Hence, here ''sda4'' is also not detected as extended partition.
+Since version 0.07 ''showmydisks'' also includes Software RAID devices (automatically or upon request as shown here):
+<code>
+user@debian:~$ ./showmydisks md
+showmydisks: warning: you probably want to be root
+> md: Software RAID (185 GB)
+|-- 0: raid1 on / as ext3 (88 MB free)
+|-- 1: raid1 fs unknown
+|-- 2: raid1 on /usr as ext3 (3 GB free)
+|-- 3: raid1 on /var as ext3 (732 MB free)
+|-- 4: raid1 on /home_u1 as ext3 (26 GB free)
+|-- 5: raid1 on /srv/backups as ext3 (16 GB free)
+</code>
+===== Limitations =====
+There are many. Some bigger ones are (we could call them "feature requests", too)
+  - Does not support disks with GUID Partition Table (GTP).
+  - Detection of filesystems of non-Linux partitions is not implemented.
+  - Detection of filesystems requires root privileges.
+  - Support for UUIDs is not implemented.
+  - LVMs are not detected.
+  - The script is not luser proof.
+===== History =====

+Please accept my sincere apology for the horrible coding style of this script. I am not a programmer, and when I started to write this script some 15 years ago my style was indeed worse than today.
