The command "lsns" is a shorthand for "list namespaces." It is used in Linux-based operating systems to display information about namespaces.
Namespaces in Linux provide a way to isolate and organize system resources. They allow multiple instances of certain resources, such as processes, network devices, or mount points, to coexist independently within the same operating system.
When you execute the "lsns" command, it provides a list of all the available namespaces on your system. It shows information such as the namespace type, its ID, a reference count, and the inode number. The output typically includes namespaces related to processes, networks, user IDs, inter-process communication, time, and mount points.
The "lsns" command can be useful for understanding the current namespace configuration on your system and identifying the different namespaces present. It provides a quick overview of how resources are organized and isolated, which can be particularly relevant in scenarios involving system-level virtualization, containers, or complex networking setups.
