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  num-
       ber.

       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 per-
       sistent namespaces without processes where the  namespace  instance  is
       held by a bind mount to /proc/pid/ns/type.


OPTIONS
       -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).

       -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 and uts.  This option may  be
	      given more than once.

       -u, --notruncate
	      Do not truncate text in columns.

       -V, --version
	      Display version information and exit.

       -h, --help
	      Display help text and exit.
