+== 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 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_.
+
+== OPTIONS
+
+*-J*, *--json*::
+Use JSON output format.
+
+*-l*, *--list*::
+Use list output format.
+
+*-n*, *--noheadings*::
+Do not print a header line.
+
+*-o*, *--output* _list_::
+Specify which output columns to print. Use *--help* to get a list of all supported columns.
++
+The default list of columns may be extended if _list_ is specified in the format **+**__list__ (e.g., *lsns -o +PATH*).
+
+*--output-all*::
+Output all available columns.
+
+*-p*, *--task* _PID_::
+Display only the namespaces held by the process with this _PID_.
+
+*-r*, *--raw*::
+Use the raw output format.
+
+*-t*, *--type* _type_::
+Display the specified _type_ of namespaces only. The supported types are *mnt*, *net*, *ipc*, *user*, *pid*, *uts*, *cgroup* and *time*. This option may be given more than once.
+
+*-u*, *--notruncate*::
+Do not truncate text in columns.
+
+*-W*, *--nowrap*::
+Do not use multi-line text in columns.
+
+*-T*, *--tree* _rel_::
+Use tree-like output format. If *process* is given as _rel_, print process tree(s) in each name space. This is default when *--tree* is not specified. If *parent* is given, print tree(s) constructed by the parent/child relationship. If *owner* is given, print tree(s) constructed by the owner/owned relationship. *owner* is used as default when _rel_ is omitted.
