[Puppet Users] How Puppet can evaluate the output od command?

Hi,

I want to run a command something like:
*cat /tmp/aao | grep aa | wc -l*
Check the output of that command,  if the output is ''0'', I
want to get a
failure from puppet.
I tried to use ''exec'' with ''returns'' but
it''s seem that ''returns'' take the
return code of the command and not the output of the command.
How can I do it right?

Re: [Puppet Users] How Puppet can evaluate the output od command?

I did not understand where exactly put the test line. I tried:
 exec { "ls":
        command => test $(grep -c aa /tmp/aao) -gt 0
        returns => 1,
        path   => "/usr/bin:/usr/sbin:/bin",
    } 
I got the error:
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: 
Could not match $(grep at /etc/puppet/.../init.pp:4 on node agent....

I need the test to run each time Puppet run.
Thank you for your quick response.

Re: [Puppet Users] How Puppet can evaluate the output od command?

The command should be in single quotes, try

exec { "ls":
command => ''test $(grep -c aa /tmp/aao) -gt 0'',
returns => 1,
path   => "/usr/bin:/usr/sbin:/bin",
}

Note also that you were missing a comma after the command property, that 
must be present.

  provider => ''sh''

to the exec.  Or, better, the command

  grep -q ''aa'' /tmp/aao

better and more simply matches your intent: it exits 0 if any match is 
found, or nonzero otherwise.  No need for wc.
