# Machine Readable Output
Every Vagrant commands accepts a `--machine-readable` flag which enables
machine readable output mode. In this mode, the output to the terminal
is replaced with machine-friendly output.
This mode makes it easy to programmatically execute Vagrant and read data
out of it. This output format is protected by our
[backwards compatibility](/v2/installation/backwards-compatibility.html)
policy. Until Vagrant 2.0 is released, however, the machine readable output
may change as we determine more use cases for it. But the backwards
compatibility promise should make it safe to write client libraries to
parse the output format.
<div class="alert alert-block alert-warn">
<p>
<strong>Advanced topic!</strong> This is an advanced topic for use only if
you want to programmatically execute Vagrant. If you're just getting started
with Vagrant, you may safely skip this section.
</p>
</div>
## Format
The machine readable format is a line-oriented, comma-delimeted text format.
This makes it extremely easy to parse using standard Unix tools such as awk or
grep in addition to full programming languages like Ruby or Python.
The format is:
```
timestamp,target,type,data...
```
Each component is explained below:
* **timestamp** is a Unix timestamp in UTC of when the message was printed.
* **target** is the target of the following output. This is empty if the
message is related to Vagrant globally. Otherwise, this is generally a machine
name so you can relate output to a specific machine when multi-VM is in use.
* **type** is the type of machine-readable message being outputted. There are
a set of standard types which are covered later.
* **data** is zero or more comma-seperated values associated with the prior
type. The exact amount and meaning of this data is type-dependent, so you
must read the documentation associated with the type to understand fully.
Within the format, if data contains a comma, it is replaced with
`%!(VAGRANT_COMMA)`. This was preferred over an escape character such as \'
because it is more friendly to tools like awk.
Newlines within the format are replaced with their respective standard escape
sequence. Newlines become a literal `\n` within the output. Carriage returns
become a literal `\r`.
## Types
This section documents all the available types that may be outputted
with the machine-readable output.
<table class="table table-hover table-bordered mr-types">
<thead>
<tr>
<th class="mr-type">Type</th>
<th>Description</th>
</tr>
</thead>
<tr>
<td>provider-name</td>
<td>
The provider name of the target machine.
<span class="label">targetted</span>
</td>
</tr>
<tr>
<td>state</td>
<td>
The state ID of the target machine.
<span class="label">targetted</span>
</td>
</tr>
<tr>
<td>state-human-long</td>
<td>
Human-readable description of the state of the machine. This is the
long version, and may be a paragraph or longer.
<span class="label">targetted</span>
</td>
</tr>
<tr>
<td>state-human-short</td>
<td>
Human-readable description of the state of the machine. This is the
short version, limited to at most a sentence.
<span class="label">targetted</span>
</td>
</tr>
