Sysbox: lsmem

Usage: lsmem [OPTION]...

List system memories or virtual spaces. This tool can print all memory chunks and virtual spaces added to the kernel. The displayed memory chunk list includes the available (regular allocatable memory) and hardware (not freely allocatable, requires exact addresses to able to allocate it) memories. The free space is also displayed for the normal (AVAIL type) memory chunks. For hardware memory chunks it is always zero.

Options:

• -a, --all
  Display all available information.
• -m, --memory
  Show memory chunks. Overrides previous -v. This is the default.
• -S, --style STYLE
  Specify the output table style. STYLE must be one of the following: raw, simple, fancy, fancyw. Default is simple.
• -v, --virtual
  Show virtual Spaces. Overrides previous -m.

Examples:
