nsenter: Run a specific command in an existing process's IPC namespace.
$ nsenter --target ${pid} --ipc ${command} ${command_arguments}
try on your machine

The command nsenter is used to enter a specified Linux namespace and execute a command within that namespace. Here is a breakdown of the given command:

  1. nsenter: This is the command itself.
  2. --target ${pid}: This option specifies the process ID (pid) of the target process in whose namespace you want to enter. It allows you to enter the same namespace as the specified process.
  3. --ipc ${command}: This option is used to enter the IPC (inter-process communication) namespace of the target process. It focuses on the communication mechanisms between processes, such as message queues or semaphores.
  4. ${command_arguments}: This is the command that you want to execute within the namespace. It can include any valid shell command or script, and its respective arguments.

To summarize, the given command instructs nsenter to enter the IPC namespace of the specified process (${pid}) and execute a command (${command}) with its corresponding arguments (${command_arguments}) within that namespace.
