Capture the output of exec command

[sateesh]

Hi,

I need to capture the output of an exec command in puppet manifest
variable. How can I do this.

Thanks in advance,
Sateesh B.

Hi Sateesh,

I need to capture the output of an exec command in puppet manifest
variable. How can I do this.

You cannot, since the manifest is compiled into a catalog on the puppet master and then the catalog is sent to the agent, which can be on a different machine, and only then is the command defined by the exec run.

Can you describe in more detail what you are actually trying to do? ( http://www.joelonsoftware.com/items/2008/01/22.html )

Cheers,

Paul

Ehrm, personly I would try:
exec {
  "put text in a file":
     command => "ls -la /etc>>/var/log/exec 2>&1";
or
     command => "ls -la /etc 2>&1 |tee /var/log/exec";

}

As Paul observed, what you ask is inconsistent with Puppet's manner of
operation. How you should proceed instead depends on what you are
trying to accomplish.

A custom fact may provide what you are looking for: you can easily add
a custom fact to your system that will run a command on the node
*before* each catalog request, and provide the output as a fact
(accessible as a top-level Puppet variable). The documentation for
custom facts (http://docs.puppetlabs.com/guides/custom_facts.html)
provides an example of exactly that.
