Oldschool Posted December 20, 2007 Share Posted December 20, 2007 I need to read a text file from the bottom... Is this possible? Large text file, and I only need last 100 lines per say, what's the best way to grab them? Something similar to ORDER BY DESC in sql Link to comment Share on other sites More sharing options...
The Ape Posted December 20, 2007 Share Posted December 20, 2007 Just an example... not tested- $count = _FileCountLines ($sFilePath) $i = $count Do If $i = 0 Then ExitLoop Else FileReadLine($sFilePath, $i) EndIf $i -= 1 Until $i = $count - 100 FixJaw.comTriad-Art.com Link to comment Share on other sites More sharing options...
Kerros Posted December 20, 2007 Share Posted December 20, 2007 Another example CODE#include<file.au3> #include<array.au3> $file = "c:\test.txt" dim $text _FileReadToArray($file,$text) $string = "" for $icc = UBound($text)-1 to UBound($text)-101 step -1 $string &= $text[$icc]&Chr(1) Next $split_string = StringSplit(StringTrimRight($string,1),Chr(1)) _ArrayDisplay($split_string) Kerros===============================================================How to learn scripting: Figure out enough to be dangerous, then ask for assistance.

The Ape Posted December 20, 2007 Share Posted December 20, 2007 (edited) Writing to an array is better. Dim $aArray $sFilePath = "some file" _FileReadToArray ( $sFilePath, $aArray ) $i = $aArray[0] Do If $i = 0 Then ExitLoop Else $Line = $aArray[$i] ;;;do something with $Line EndIf $i -= 1 Until $i = $aArray[0] - 100oÝ÷ Ø[¥ +)à{¦¦WºÚ"µÍÚ[ÛYIÙ[K]LÉÝÂÚ[ÛYIØ^K]LÉÝÂ[H ÌÍØP^BÌÍÙÝZHHÕRPÜX]J ][ÝÙ^[I][ÝË LKLJBÌÍØ]ÛHÕRPÝÜX]P]Û ][ÝÛÜ[][ÝË L BÌÍÙY]HÕRPÝÜX]QY] ][ÝÉ][ÝË Î BÕRTÙ]Ý]J BÚ[HB ÌÍÛÙÈHÕRQÙ]ÙÊ BÙ[XÝØÙH ÌÍÛÙÈH ÌÍØ]Û ÌÍÜÑ[T]H[SÜ[X[ÙÊ ][ÝÓÜ[][ÝË ][ÝÉ][ÝË ][ÝÕ^[Ê I][ÝÊBYÜ[ÎÎÎÎÂ[ÙBÕRPÝÙ]]J ÌÍÙY] ][ÝÉ][ÝË ][ÝÉ][ÝÊBÑ[TXYÐ^H ÌÍÜÑ[T] ÌÍØP^H B ÌÍÚHH ÌÍØP^VÌBÂY ÌÍÚHH[^]ÛÜ[ÙB ÌÍÓ[HH ÌÍØP^VÉÌÍÚWBÕRPÝÙ]]J ÌÍÙY] ÌÍÓ[I[ÐÔ B[Y ÌÍÚHOHB[[ ÌÍÚHH ÌÍØP^VÌHHL[YØÙH ÌÍÛÙÈH ÌÍÑÕRWÑUSÐÓÔÑB^][Ù[XÝÙ[ÕRQ[]H B^] Edited December 20, 2007 by The Ape FixJaw.comTriad-Art.com Link to comment Share on other sites More sharing options...
Oldschool Posted December 20, 2007 Author Share Posted December 20, 2007 (edited) Cool thanks, I got it: Dim $aRecords If Not _FileReadToArray("text.txt",$aRecords) Then MsgBox(4096,"Error", " Error reading log to Array error:" & @error) Exit EndIf For $x = $aRecords[0] - 40 to $aRecords[0] ;Msgbox(0,'Record:' & $x, $aRecords[$x]) If StringInStr($aRecords[$x], "Some Value") Then Local $var = StringMid($aRecords[$x], 7, 15) MsgBox(0, "", $var) ExitLoop EndIf Next Edited December 20, 2007 by Oldschool Link to comment Share on other sites More sharing options...
randallc Posted December 20, 2007 Share Posted December 20, 2007 Hi, If you want to only read the end, rather than waiting for the whole file, much quicker to use TailRW UDF (link in sig) Best, Randall ExcelCOM...

MrCreatoR Posted December 21, 2007 Share Posted December 21, 2007 You can also read the file from the bottom like this: $FilePath = "Test.txt" $sRead = FileRead($FilePath) $100Lines = StringTrimLeft($sRead, StringInStr($sRead, @CRLF, "", -101)+1) ConsoleWrite($100Lines) Spoiler Using OS: Win 7 Professional, Using AutoIt Ver(s): 3.3.6.1 / 3.3.8.1 AutoIt Russian Community My Work...
