Puppet::Type.newtype(:file_line) do
desc <<-EOT
Ensures that a given line is contained within a file. The implementation
matches the full line, including whitespace at the beginning and end. If
the line is not contained in the given file, Puppet will append the line to
the end of the file to ensure the desired state. Multiple resources may
be declared to manage multiple lines in the same file.
Example:
file_line { 'sudo_rule':
path => '/etc/sudoers',
line => '%sudo ALL=(ALL) ALL',
}
file_line { 'sudo_rule_nopw':
path => '/etc/sudoers',
line => '%sudonopw ALL=(ALL) NOPASSWD: ALL',
}
In this example, Puppet will ensure both of the specified lines are
contained in the file /etc/sudoers.
Match Example:
file_line { 'bashrc_proxy':
ensure => present,
path => '/etc/bashrc',
line => 'export HTTP_PROXY=http://squid.puppetlabs.vm:3128',
match => '^export\ HTTP_PROXY\=',
}
In this code example match will look for a line beginning with export
followed by HTTP_PROXY and replace it with the value in line.
Match Example With `ensure => absent`:
file_line { 'bashrc_proxy':
ensure => absent,
path => '/etc/bashrc',
line => 'export HTTP_PROXY=http://squid.puppetlabs.vm:3128',
match => '^export\ HTTP_PROXY\=',
match_for_absence => true,
}
In this code example match will look for a line beginning with export
followed by HTTP_PROXY and delete it. If multiple lines match, an
error will be raised unless the `multiple => true` parameter is set.
**Autorequires:** If Puppet is managing the file that will contain the line
being managed, the file_line resource will autorequire that file.
