I need to replace some text in a file... there is some type, that i can pass a value and to be replace and the destination file? or anyone here have some class who does that? -- Marley Bacelar Project Fedora Ambassador VCP, VSP.

You might want to check out Augeas. It might be easier to use. I''ve seen a simple define that does that, but I can''t find it. It had a grep statement in unless, and used sed to make the change.

You would almost certainly be better off copying the right file content into place, so that you don''t have the extra complexity. As an alternative, building the file from fragments with one of the ''concatenated files'' classes is a pretty sound idea; it makes it easy have variable sections inside the file without needing to edit-in-place.> or anyone here have some class who does that?There are a couple in the common module collections; check out the wiki for the links off to ''em. Their current state may have changed since I last looked, so I don''t have a specific recommendation for you. Daniel Y''see, I learned that lesson way back when cfengine provided really good tools for doing this sort of editing, and it *always* tool much longer and was much less robust than I expected... -- ✣ Daniel Pittman ✉ daniel@rimspace.net ☎ +61 401 155 707 ♽ made with 100 percent post-consumer electrons -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Generally we do this because we want to allow people to customize extra parts of their config files, and we''ve switched daemons entirely for some services, simply based upon their ability to cope with a parts.d directory or to have "include" directives of some kind. That allows you to ship an absolute config with a default include that people are free to modify. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Very nice feature to give users some rights without loosing control of the file or its structure. It wouldn''t be too hard to extend it to make arbitrary user supplied .d directories for daemons that dont support those :) http://github.com/ripienaar/puppet-concat -- R.I.Pienaar -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Nice... I solved my probleman using the:
define replace($file, $pattern, $replacement) {
exec { "/usr/bin/perl -pi -e ''s/$pattern/$replacement/''
''$file''":
onlyif => "/usr/bin/perl -ne ''BEGIN { \$ret = 1; } \$ret
= 0 if
/$pattern/ && ! /$replacement/ ; END { exit \$ret; }''
''$file''",
}
}
Then i my class used:
replace { "/etc/bashrc":
file => "/etc/bashrc",
pattern => "PS1",
replacement => "PS1 DOMAINA.COM"
}
Worked perfectly... Know i will see the other options proposed here. Thank
you evry much guys
