<H2>DESCRIPTION</H2>
|
|
|
|
<B>lsns</B>
|
|
|
|
lists information about all the currently accessible namespaces or about the
|
|
given <I>namespace</I>. The <I>namespace</I> identifier is an inode number.
|
|
<P>
|
|
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 <B>--output</B> option together with a columns list in
|
|
environments where a stable output is required.
|
|
<P>
|
|
<B>NSFS</B> column, printed when <B>net</B> is specified for
|
|
<B>--type</B> option, is special; it uses multi-line cells.
|
|
Use the option <B>--nowrap</B> is for switching to "," separated single-line
|
|
representation.
|
|
<P>
|
|
Note that <B>lsns</B> 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 <B>unshare --mount-proc</B> for more details).
|
|
<B>lsns</B>
|
|
|
|
is not able to see persistent namespaces without processes where the namespace
|
|
instance is held by a bind mount to /proc/<I>pid</I>/ns/<I>type</I>.
