>Description:
When you use fdisk in interactive mode, you never know which id refers to the partition type, e.g :
11 refers to MS-Dos
165 regers to BSD.
etc...
This patch add a -l flag to fdisk(8) to show all partitions types, the following output will be printed like that :
markand@Melon ~ $ fdisk -l
