lsns — list namespaces
lsns [options]
[namespace]
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.

−l,
−−listUse list output format.
−n,

The default list of columns may be extended if

lsns −o
+PATH).
−p,
−−task pidDisplay only the namepsaces held by the process with this pid.
−r,
−−rawUse the raw output format.
−t,
