augeas($action, @options)

It returns 1 on success and 0 on failure.

Actions:

modify

This modifies the keys given in @options in $file.

 augeas modify =>
           "/files/etc/hosts/7/ipaddr"    => "127.0.0.2",
           "/files/etc/hosts/7/canonical" => "test01",
           on_change                      => sub { say "I changed!" };
