       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!" };

            augeas remove    => "/files/etc/hosts/2",

       insert
           Insert an item into the file. Here, the order of the options is important. If the

                      ipaddr    => "192.168.2.23",
                      alias     => "test02",
                      on_change => sub { say "I changed!" };

       dump
           Dump the contents of a file to STDOUT.

            augeas dump => "/files/etc/hosts";

       exists
           Check if an item exists.

            my $exists = augeas exists => "/files/etc/hosts/*/ipaddr" => "127.0.0.1";
            if($exists) {
                say "127.0.0.1 exists!";
            }

       get Returns the value of the given item.

            my $val = augeas get => "/files/etc/hosts/1/ipaddr";
