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
-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
