[Puppet Users] How to store "bash command:" output in a variable as array

exec {''ls'':
       command => "ls",
       path => "/usr/bin:/bin",
       provider => shell,
}

So the output of "ls" contains files/directories, these should be
stored in
a array for suppose "$my_array" and it should be used globally in the 
module.

Can any one help me in  this

Re: [Puppet Users] How to store "bash command:" output in a variable as array

Hi,

You should have a look at ''facts''.

An exec is executed in the last phase of a puppet run.  If you need 
information form a node, that you need in eg. templates, modules etc, 
you will have to use facts.

Have a look at the last image on http://puppetlabs.com/puppet/what-is-puppet

Writing simple custom facts is not that difficult.

Re: [Puppet Users] How to store "bash command:" output in a variable as array

Hi y''all,
creating custom fact is great. If you need it just for testing, use 
generate.

$arr = generate(''/bin/ls'')
Btw: the difference between exec and generate is that generate is executed 
right on the beginning of Puppet run (so it will fail if it''s using
tool
installed later by Puppet). You will get only exit code from exec, not the 
output.

No. The difference is that generate() is run on the master and exec on the 
agent: http://docs.puppetlabs.com/references/latest/function.html#generate
