Synopsis
free [options
]
The free
command displays
memory usage in kilobytes:
$ free total used free shared buffers cached Mem: 523812 491944 31868 0 67856 199276 -/+ buffers/cache: 224812 299000 Swap: 530104 0 530104
The Linux kernel reserves as much memory as possible for
caching purposes, so your best estimate of free RAM in the preceding
output is in the buffers/cache
row, free
column (i.e.,
299000K).
