These options control the format of output from the list and find
commands.
-f format
--format=format
Sets the type of table formatting. The following
types of format are available:
table 2-D text tables with aligned columns.
list (default)
A list with one column per line and rows
separated by a blank line.
html HTML tables.
csv Comma-separated values as defined in RFC 4180.
json JSON format as defined in RFC 4627. The output
is a sequence of JSON objects, each of which
corresponds to one table. Each JSON object has
the following members with the noted values:
caption
The table's caption. This member is
omitted if the table has no caption.
headings
An array with one element per table
column. Each array element is a string
giving the corresponding column's
heading.
data An array with one element per table
row. Each element is also an array with
one element per table column. The
elements of this second-level array are
the cells that constitute the table.
Cells that represent OVSDB data or data
types are expressed in the format
described in the OVSDB specification;
other cells are simply expressed as
text strings.
-d format
--data=format
Sets the formatting for cells within output tables
unless the table format is set to json, in which case
json formatting is always used when formatting cells.
The following types of format are available:
string (default)
The simple format described in the Database
Values section of ovs-vsctl(8).
bare The simple format with punctuation stripped
off: [] and {} are omitted around sets, maps,
and empty columns, items within sets and maps
are space-separated, and strings are never
quoted. This format may be easier for scripts
to parse.
json The RFC 4627 JSON format as described above.
--no-headings
This option suppresses the heading row that otherwise
appears in the first row of table output.
--pretty
By default, JSON in output is printed as compactly as
possible. This option causes JSON in output to be
printed in a more readable fashion. Members of
objects and elements of arrays are printed one per
line, with indentation.
This option does not affect JSON in tables, which is
always printed compactly.
--bare
Equivalent to --format=list --data=bare
--no-headings.
PKI Options
PKI configuration is required to use SSL for the connection to
the database.
-p privkey.pem
--private-key=privkey.pem
Specifies a PEM file containing the private key used
as identity for outgoing SSL connections.
-c cert.pem
--certificate=cert.pem
Specifies a PEM file containing a certificate that
certifies the private key specified on -p or
--private-key to be trustworthy. The certificate must
be signed by the certificate authority (CA) that the
peer in SSL connections will use to verify it.
-C cacert.pem
--ca-cert=cacert.pem
Specifies a PEM file containing the CA certificate
for verifying certificates presented to this program
by SSL peers. (This may be the same certificate that
SSL peers use to verify the certificate specified on
-c or --certificate, or it may be a different one,
depending on the PKI design in use.)
-C none
--ca-cert=none
Disables verification of certificates presented by
SSL peers. This introduces a security risk, because
it means that certificates cannot be verified to be
those of known trusted hosts.
--bootstrap-ca-cert=cacert.pem
When cacert.pem exists, this option has the same
effect as -C or --ca-cert. If it does not exist,
then the executable will attempt to obtain the CA
certificate from the SSL peer on its first SSL
connection and save it to the named PEM file. If it
is successful, it will immediately drop the
connection and reconnect, and from then on all SSL
connections must be authenticated by a certificate
signed by the CA certificate thus obtained.
This option exposes the SSL connection to a man-in-
the-middle attack obtaining the initial CA
certificate, but it may be useful for
bootstrapping.
This option is only useful if the SSL peer sends
its CA certificate as part of the SSL certificate
chain. The SSL protocol does not require the server
to send the CA certificate.
This option is mutually exclusive with -C and
--ca-cert.
Other Options
-h
--help
Prints a brief help message to the console.
-V
--version
Prints version information to the console.
