.SH DESCRIPTION
Lists contents of the EC2 instance store. The \fIPATH\fR argument
specifies the pathname to list. It is relative to
.BR http://169.254.169.254/latest .
If \fIPATH\fR ends with a slash, it is treated as a directory and
its content is listed. Otherwise, it is treated as a file.
.PP
Optional \fIKEY\fR arguments are allowed when listing content of a
file. If one or more \fIKEY\fRs are given, the file is parsed as
a JSON object. For each \fIKEY\fR, a corresponding value is looked
up in the resulting object and printed on a separate line, prefixed
with \fIKEY\fR and a colon.
.PP
The utility must be run from a EC2 instance.
.SH OPTIONS
.TP
\fB\-b\fR, \fB\-\-base=\fIURL\fR
Base URL to use, instead of
.BR http://169.254.169.254/latest .
.TP
\fB\-d\fR, \fB-\-debug\fR
Increase debugging level.
.TP
\fB\-p\fR, \fB\-\-port=\fINUMBER\fR
Set remote port number, instead of the default \fB80\fR.
.PP
Following option applies only when listing directories:
.TP
\fB\-r\fR, \fB\-\-recursive
List directories recursively.
.PP
The options below configure output if at least one \fIKEY\fR is given:
.TP
\fB\-D\fR, \fB\-\-delimiter=\fISTRING\fR
Delimit output values with \fISTRING\fR. Default delimiter is a colon.
.TP
\fB\-N\fR, \fB\-\-names
Print key names.
.TP
\fB\-Q\fR, \fB\-\-quote\fR
Quote string values. String values will be enclosed in
double-quotes. Double-quote and backslash characters appearing within
strings will be escaped with backslashes.
.TP

Print type character. Type characters are:
.BR 0 ,
for \fBnull\fR values,

for booleans,
.BR n ,
for numeric values,
.BR s ,
for strings ,
.BR a ,
for arrays, and
.BR o ,
for objects.
