How to store "bash command:" output in a variable as array

[sasikiran v]

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

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.

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

Sorry for confusion, I'm used to masterless Puppet...
