Ace,
in this simple case, you could probably get away with
define appendifnosuchline($file="", $line="") {
exec { "appendline_${file}_${line}":
path => "/bin:/usr/bin",
command => "/bin/echo ${line} >> ${file}",
unless => "grep -qx ${line} ${file}",
require => File[$file],
}
}
Note the require parameter to the exec resource. This will prevent you
from using this define on non-puppetmanaged files though. For more
flexibility:
define appendifnosuchline($file="", $line="", $disable_autorequire =>
false) {
if !$disable_autorequire {
Exec { require => File[$file] }
}
exec { "appendline_${file}_${line}":
path => "/bin:/usr/bin",
command => "/bin/echo ${line} >> ${file}",
unless => "grep -qx ${line} ${file}",
}
}
Then specify "disable_autorequire => true" where applicable.
The third route is not to touch the define at all and add the require
each time you declare it as a resource. But that's redundant, and we
don't like that.
There, much safer now ;)
Cheers,
Felix
