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 cur-
       rent /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).

       -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 and cgroup.  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.
