Синопсис (Synopsis)
lsmem [options]
Описание (Description)
The lsmem command lists the ranges of available memory with their
online status. The listed memory blocks correspond to the memory
block representation in sysfs. The command also shows the memory
block size and the amount of memory in online and offline state.
The default output compatible with original implementation from
s390-tools, but it's strongly recommended to avoid using default
outputs in your scripts. Always explicitly define expected
columns by using the --output option together with a columns list
in environments where a stable output is required.
The lsmem command lists a new memory range always when the
current memory block distinguish from the previous block by some
output column. This default behavior is possible to override by
the --split option (e.g., lsmem --split=ZONES). The special word
"none" may be used to ignore all differences between memory
blocks and to create as large as possible continuous ranges. The
opposite semantic is --all to list individual memory blocks.
Note that some output columns may provide inaccurate information
if a split policy forces lsmem to ignore differences in some
attributes. For example if you merge removable and non-removable
memory blocks to the one range than all the range will be marked
as non-removable on lsmem output.
Not all columns are supported on all systems. If an unsupported
column is specified, lsmem prints the column but does not provide
any data for it.
Use the --help option to see the columns description.
Параметры (Options)
-a, --all
List each individual memory block, instead of combining
memory blocks with similar attributes.
-b, --bytes
Print the SIZE column in bytes rather than in a
human-readable format.
-h, --help
Display help text and exit.
-J, --json
Use JSON output format.
-n, --noheadings
Do not print a header line.
-o, --output list
Specify which output columns to print. Use --help to get a
list of all supported columns. The default list of columns
may be extended if list is specified in the format +list
(e.g., lsmem -o +NODE).
--output-all
Output all available columns.
-P, --pairs
Produce output in the form of key="value" pairs. All
potentially unsafe value characters are hex-escaped
(\x<code>).
-r, --raw
Produce output in raw format. All potentially unsafe
characters are hex-escaped (\x<code>).
-S, --split list
Specify which columns (attributes) use to split memory blocks
to ranges. The supported columns are STATE, REMOVABLE, NODE
and ZONES, or "none". The other columns are silently ignored.
For more details see DESCRIPTION above.
-s, --sysroot directory
Gather memory data for a Linux instance other than the
instance from which the lsmem command is issued. The
specified directory is the system root of the Linux instance
to be inspected.
-V, --version
Display version information and exit.
--summary[=when]
This option controls summary lines output. The optional
argument when can be never, always or only. If the when
argument is omitted, it defaults to "only". The summary
output is suppressed for --raw, --pairs and --json.
