Hi all,
I''m trying to run the code below. Basically I want to include the users
"user" and "user2" after the line
"Authentication:". I''m running this
ruby_block inside a Chef recipe and in a first moment it works as
expected, however, after I run "chef-solo" again the recipe is applied
again and two more lines are created in the destination file. I need a
way for my script to check for the existence of "user" and
"user2" lines
and then stop the script and write nothing.
I suspect I should use some kind of regular expression but I am not sure
how.
Any ideas? Below follows the code.
Thanks for your help.
*ruby_block "insert_line_to_sshd" do**
** block do**
** file = Chef::Util::FileEdit.new("/tmp/testconf")**
** file.insert_line_after_match("Authentication:",
"AllowUsers/1 user")**
** file.insert_line_after_match("Authentication:",
"AllowUsers/1
user2")**
** file.write_file**
** end**
**end*

You shouldn''t need a Regex for that, how about String#include? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

What you could do is call search_file_delete_line for the two lines you’re adding. Hacky, but it should work every time. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
