ispeek - EC2 instance store lister

SYNOPSIS

ispeek [-NQTdr] [-D STRING] [-b URL] [-p NUMBER] [--base-url=URL] [--delimiter=STRING] [--names] [--quote] [--type] [--port=NUMBER] PATH [KEY...]
ispeek [-Vh] [--help] [--usage] [--version]

DESCRIPTION

Lists contents of the EC2 instance store. The PATH argument specifies the pathname to list. It is relative to http://169.254.169.254/latest. If PATH ends with a slash, it is treated as a directory and its content is listed. Otherwise, it is treated as a file.

Optional KEY arguments are allowed when listing content of a file. If one or more KEYs are given, the file is parsed as a JSON object. For each KEY, a corresponding value is looked up in the resulting object and printed on a separate line, prefixed with KEY and a colon.

The utility must be run from a EC2 instance.

OPTIONS

-b, --base=URL

Base URL to use, instead of http://169.254.169.254/latest.

-d, --debug

-p, --port=NUMBER

Following option applies only when listing directories:

The options below configure output if at least one KEY is given:

-D, --delimiter=STRING

Delimit output values with STRING. Default delimiter is a colon.

-N, --names

Print key names.

-Q, --quote

Quote string values. String values will be enclosed in double-quotes. Double-quote and backslash characters appearing within strings will be escaped with backslashes.

-T, --type

Print type character. Type characters are: 0, for null values, b, for booleans, n, for numeric values, s, for strings , a, for arrays, and o, for objects.

The order of printing is: key name, type, value.

-V, --version

Print program version.

-h, --help

Give a concise help summary.
