sweet, that did the trick. Although I still had issues viewing the file because of the - inside the name, so I just renamed it again to new.dat using your syntax above, and now tail doesn't complain.
Thanks for this!

LEARN ABOUT PHP
array_walk_recursive
ARRAY_WALK_RECURSIVE(3) 1 ARRAY_WALK_RECURSIVE(3)
array_walk_recursive - Apply a user function recursively to every member of an array
SYNOPSIS
bool array_walk_recursive NULL (array &$array, callable $callback, [mixed $userdata])
DESCRIPTION
Applies the user-defined $callback function to each element of the $array. This function will recurse into deeper arrays.
PARAMETERS
o $array
- The input array.
o $callback
- Typically, $callback takes on two parameters. The $array parameter's value being the first, and the key/index second.
Note
If $callback needs to be working with the actual values of the array, specify the first parameter of $callback as a refer-
ence. Then, any changes made to those elements will be made in the original array itself.
o $userdata
- If the optional $userdata parameter is supplied, it will be passed as the third parameter to the $callback.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
array_walk_recursive(3) example
<?php
$sweet = array('a' => 'apple', 'b' => 'banana');
$fruits = array('sweet' => $sweet, 'sour' => 'lemon');
function test_print($item, $key)
{
echo "$key holds $item
";
}
array_walk_recursive($fruits, 'test_print');
?>
The above example will output:
a holds apple
b holds banana
sour holds lemon
You may notice that the key ' sweet' is never displayed. Any key that holds an array will not be passed to the function.
