FileRead question

[Ultratuga]

This should be easy, but i´m not seeing how...

How to read the content of a text file from line 20 until the end?

Stringsplit ?

One way...

$sFilePath = @ScriptDir & "\test.txt"
$iLineCount = 19

$hFileOpen = FileOpen($sFilePath)

$sFileRead = ""
While 1
    $iLineCount = $iLineCount + 1
    $sLine = FileReadLine($hFileOpen, $iLineCount)
    If @error Then ExitLoop
    $sFileRead &= $sLine & @CRLF
WEnd

FileClose($hFileOpen)

MsgBox(0, "", $sFileRead)

Perfect. Thanks

$txt = FileRead("1.txt")
$txt = StringRegExpReplace($txt, '(.*\R){19}', "")

Msgbox(0,"", $txt)

I really like that creative use of stringregexpreplace there, but im having trouble understanding exactly what it is doing.

the result when i test it is as expected, but the syntax you used doesnt seam to match the help file, and i cant figure out what "pattern" you are actually telling it to look for. i could find  r  in help file but not  R

this is my first time even looking at stringregexp and now i have a headache.

edit: just looked in the online help file, which apparently has a LOT more info than the help file that opens from SciTE

so it looks like it would match 0 or more of any character that are followed by a carriage return, up to the count of 19, replace them with "" (blank), leaving only what is left over, which would be from line 20 and on?

brilliant!

You need a recent release (or beta) of AutoIt to see the detailed discussion of regexp patterns.

While not truly exhaustive it still covers most uses.
