NAME
lsns - list namespaces
SYNOPSIS
lsns
[options]
[ namespace]
DESCRIPTION
lsns
lists information about all the currently accessible namespaces or about the
given namespace. The namespace identifier is an inode number.
The default output is subject to change. So whenever possible, you should
avoid using default outputs in your scripts. Always explicitly define expected
columns by using the --output option together with a columns list in
environments where a stable output is required.
Note that lsns reads information directly from the /proc filesystem and
for non-root users it may return incomplete information. The current /proc
filesystem may be unshared and affected by a PID namespace
(see unshare --mount-proc for more details).
lsns
is not able to see persistent namespaces without processes where the namespace
instance is held by a bind mount to /proc/pid/ns/type.
