список пространств имен (list namespaces)
Имя (Name)
lsns - list namespaces
Синопсис (Synopsis)
lsns
[options] namespace
Описание (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 output mode (--tree
or --list
) and
columns by using the --output
option together with a columns list
in environments where a stable output is required.
The NSFS
column, printed when net
is specified for the --type
option, is special; it uses multi-line cells. Use the option
--nowrap
to switch to ","-separated single-line representation.
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.
