список пространств имен (list namespaces)
Имя (Name)
lsns - list namespaces
Синопсис (Synopsis)
lsns [options] namespace
Описание (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.
Параметры (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 proecss 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.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
