ec2-describe-keypairs

Description

Returns information about key pairs available to you. If you specify key pairs, information about those key pairs is returned. Otherwise, information for all your key pairs is returned.

You can filter the results to return information only about key pairs that match criteria you specify. For example, you could filter the results to return only the key pairs whose names include the string Dave. You can specify multiple values for a filter. A key pair must match at least one of the specified values for it to be included in the results.

You can specify multiple filters (e.g., the key pair name includes the string Dave, and the fingerprint equals a certain value). The result includes information for a particular key pair only if it matches all your filters. If there's no match, no special message is returned; the response is simply empty.

You can use wildcards with the filter values: * matches zero or more characters, and ? matches exactly one character. You can escape special characters using a backslash before the character. For example, a value of \*amazon\?\\ searches for the literal string *amazon?\.

The following table shows the available filters.

Filter Name Description

fingerprint

Fingerprint of the key pair.

Type: String

key-name

Name of the key pair.

Type: String

The short version of this command is ec2dkey.

Syntax

ec2-describe-keypairs [keypair_name ...] [[--filter name=value] ...]

Options

NameDescriptionRequired

keypair_name

Name of the key pair to describe.

Type: String

Default: Describes all key pairs you own, or only those otherwise specified.

Example: gsg-keypair

No

--filter name=value

A filter for limiting the results. See the preceding table for a list of allowed filter names and values. If you're using the command line tools on a Windows system, you might need to use quotation marks (i.e., "name=value").

Type: String

Default: Describes all key pairs you own, or only those otherwise specified.

Example: --filter "tag-name=*Dave*"

No

Common Options

OptionDescription

--region REGION

Overrides the Region specified in the EC2_URL environment variable and the URL specified by the -U option.

Default: The EC2_URL environment variable, or us-east-1 if the environment variable is not set.

Example: --region eu-west-1

-U, --url URL

URL is the uniform resource locator of the Amazon EC2 web service entry point.

Default: The EC2_URL environment variable, or https://ec2.amazonaws.com if the environment variable is not set.

Example: -U https://ec2.amazonaws.com

-K, --private-key EC2-PRIVATE-KEY

The private key to use when constructing requests to Amazon EC2.

Default: The value of the EC2_PRIVATE_KEY environment variable.

Example: -K pk-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem

-C, --cert EC2-CERT

The X.509 certificate to use when constructing requests to Amazon EC2.

Default: The value of the EC2_CERT environment variable.

Example: -C cert-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem

--connection-timeout TIMEOUT

Specifies a connection timeout (in seconds).

Example: --connection-timeout 30

--request-timeout TIMEOUT

Specifies a request timeout (in seconds).

Example: --request-timeout 45

-v, --verbose

Displays verbose output by showing the SOAP request and response on the command line. This is particularly useful if you are building tools to talk directly to our SOAP API.

-H, --headers

Displays column headers in the output.

--show-empty-fields

Shows empty columns as (nil).

--hide-tags

Do not display tags for tagged resources.

--debug

Prints internal debugging information. This is useful to assist us when troubleshooting problems.

-?, --help, -h

Displays Help.

-

If - is specified as an argument to one of the parameters, a list of arguments is read from standard input. This is useful for piping the output of one command into the input of another.

Example: ec2-describe-instances | grep stopped | cut -f 2 | ec2-start-instances -

Output

The command returns a table that contains the following information:

  • KEYPAIR identifier

  • Key pair name

  • Private key fingerprint

Amazon EC2 command line tools display errors on stderr.

Examples

Example Request

This example describes the keypair with name gsg-keypair.

PROMPT> ec2-describe-keypairs gsg-keypair
KEYPAIR    gsg-keypair    1f:51:ae:28:bf:89:e9:d8:1f:25:5d:37:2d:7d:b8:ca:9f:f5:f1:6f

Example Request

This example filters the results to display only key pairs whose names include the string Dave.

PROMPT> ec2-describe-keypairs --filter "key-name=*Dave*"
