ipcrm

Remove System V IPC objects.

systemadmininspect

Additional Notes

ipcrm is a system command used to remove System V IPC objects. It is used to clean up stale shared memory segments, semaphores, or message queues left by crashed or orphaned processes.

Use ipcs first to inspect active IPC objects and their IDs before removing them with ipcrm. Removing an IPC object can affect running processes that rely on it.

Parameters

  • options: Flags that change how ipcrm behaves.
  • 'id': IPC object ID(s) to remove.

Common Options

  • --help: Show command help when supported.
  • --version: Show version information when supported.

ipcrm --help
man ipcrm

Practical Notes

Options can vary by distribution and package version. Use man ipcrm, ipcrm --help, or the package documentation for exact syntax.
