LSIPC(1) LSIPC(1) lsipc - IPC lsipc [] lsipc shows information on the POSIX and System V inter-process communication facilities for which the calling process has read access. The default output, as well as the default output from options with predefined output columns (like --shmems, etc.), is subject to change. So whenever possible, you should avoid using default outputs in your scripts. Always explicitly define expected columns by using --output columns-list in environments where a stable output is required. -i, --id Show full details on just the one resource element (System V) 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. -N, --name Show full details on just the one resource element (POSIX) identified by name. 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 IPC . : -m, -q -s. . -h, --help . -V, --version Display version and exit. -m, --shmems Write information about active System V shared memory segments. -M, --posix-shmems Write information about active POSIX shared memory segments. -q, --queues Write information about active System V message queues. -Q, --posix-mqueues Write information about active POSIX message queues. -s, --semaphores Write information about active System V semaphore sets. -S, --posix-semaphores Write information about active POSIX named semaphores. -c, --creator . -e, --export ="". - (\x<o>). --shell. -J, --json JSON . -l, --list . , --id. -n, --newline . --noheadings . --notruncate . -o, --output . --help . -b, --bytes . -r, --raw ( ). -t, --time . , msgsnd(2) msgrcv(2) , shmat(2) shmdt(2) , semop(2) . --time-format , . , . -P, --numeric-perms . -y, --shell . , , --export. --export 2.37, , --shell. 0 ,, ", 1 , 2 . lsipc ipcs(1) .
