LSNS(8)                               System Administration                               LSNS(8)



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 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.


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.
