lsns: List namespaces, only showing the namespace ID, type, PID, and command.

lsns

$ lsns --output NS,TYPE,PID,COMMAND

try on your machine

The lsns command is used to list information about various Linux namespaces on the system. Namespaces provide a way to isolate and virtualize certain elements of the operating system, such as process IDs, network interfaces, mount points, etc.

In this specific command, lsns is used with the --output NS,TYPE,PID,COMMAND flag to specify the format of the output. Here's what each field in the output means:

NS: The namespace ID, a unique identifier for a namespace.
TYPE: The type of the namespace, such as pidns for process namespace, netns for network namespace, etc.
PID: The process ID of the process that owns the namespace.
COMMAND: The command or process name associated with the namespace.

By running this command, you will receive a list of namespaces along with their types, the process that owns them, and the command/process name associated with them. This can help you understand the namespace hierarchy and relationships between different processes on the system.
