Filereadline from end of file

[SublimePorte]

I am trying to read a file line by line from the end.

According to docs:

[optional] The line number to read. The first line of a text file is line 1 (not zero), last line is -1.

One would assume that -2 would be the second last line and so on, yet it doesn't appear to be the case.

Any way to read a file line by line from the end?

Hi,

#include <file.au3>
;file to open
$file = "test.txt"
;open file in read mode
$filehnd = FileOpen ($file, 0)
;loop reading lastline to first line
For $i = _FileCountLines ($file) To 1 Step - 1
    $line = FileReadLine ($filehnd, $i)
    MsgBox (0,"",$line)
Next
FileClose($file)

;-))

@edit: Array solution:

#include <file.au3>
Global $arlines
$file = "test.txt"
_FileReadToArray ($file, $arlines)
For $i = $arlines [0] To 1 Step - 1
    MsgBox (0,"", $arlines [$i])
Next

Ahh should've checked the udf's for a function to countlines. Thanks.
