LSIPC(1) User Commands LSIPC(1)
lsipc - show information on IPC facilities currently employed in
the system
lsipc [options]
lsipc shows information on the System V inter-process
communication facilities for which the calling process has read
access.
-i, --id id
Show full details on just the one resource element
identified by id. This option needs to be combined with
one of the three resource options: -m, -q or -s. It is
possible to override the default output format for this
option with the --list, --raw, --json or --export option.
-g, --global
Show system-wide usage and limits of IPC resources. This
option may be combined with one of the three resource
options: -m, -q or -s. The default is to show information
about all resources.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
Resource options
-m, --shmems
Write information about active shared memory segments.
-q, --queues
Write information about active message queues.
-s, --semaphores
Write information about active semaphore sets.
Output formatting
-c, --creator
Show creator and owner.
-e, --export
Produce output in the form of key="value" pairs. All
potentially unsafe value characters are hex-escaped
(\x<code>). The key (variable name) will be modified to
contain only characters allowed for a shell variable
identifiers, for example, USE_PCT instead of USE%.
-J, --json
Use the JSON output format.
-l, --list
Use the list output format. This is the default, except
when --id is used.
-n, --newline
Display each piece of information on a separate line.
--noheadings

-o, --output list
Specify which output columns to print. Use --help to get
a list of all supported columns.
-b, --bytes
Print size in bytes rather than in human readable format.
-r, --raw
Raw output (no columnation).
-t, --time
Write time information. The time of the last control
operation that changed the access permissions for all
facilities, the time of the last msgsnd(2) and msgrcv(2)
operations on message queues, the time of the last
shmat(2) and shmdt(2) operations on shared memory, and the
time of the last semop(2) operation on semaphores.
--time-format type
Display dates in short, full or iso format. The default
is short, this time format is designed to be space
efficient and human readable.
-P, --numeric-perms
Print numeric permissions in PERMS column.
0 if OK,

The lsipc utility is inspired by the ipcs utility.
