lsipc - show information on IPC facilities currently employed in the system
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 Output data in the format of NAME=VALUE. -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 Do not print a header line. --notruncate Don't truncate output. -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, 1 if incorrect arguments specified, 2 if a serious error occurs.
The lsipc utility is inspired by the ipcs utility.
