I would like to search over 100 text files for a certain word, and then display that line, which has the certain word in, into a another text file?
Is that possible?

It'd be quite easy in PHP...

Yeah i know its possible in linux, just wondering if there was any way possible in windows?

Take a look at this article, and also look at all the comments (lots of related programs, including cygwin ).

python would be eaiser, use regex in python, if you need me to write something, pm or post

If all the text files are in the same directory, open a command prompt in that directory and run...

find "word" *.txt > ..\results.txt

(The results file is in the parent directory so it won't be included in the search =p)

You could also use a text editor with a "find in files" feature, like PSPad or Notepad++ or EditPlus.

Thanks WDZ

How? =O

---

php code:

---

$needle = 'needle'; //value to search in the text files
$dir = './dir/'; //dir to folder containing text files

$files = scandir($dir);
$arr_count = count($files);
$i = 0;
$cur_file = current($files);

while ($i<$arr_count){
    $ext = substr($cur_file, strrpos($cur_file,'.') + 1);
    if($ext == 'txt'){
        $line_array = file($dir.$cur_file);
        $line_count = count(file($dir.$cur_file));
        $n = 1;
        $cur_line = current($line_array);
        while ($n <= $line_count){
            if(strpos($cur_line,$needle) !== FALSE){
                $line_quote = str_replace($needle,"<b>".$needle."</b>",$cur_line);
                echo"Found value in $dir"."$cur_file <br /> $n - $line_quote";
                exit;
            }
            $n++;
            $cur_line = next($line_array);
        }
    }
    $i++;
    $cur_file = next($files);
}

Not nearly as easy as WDZ's method above, but just for completion and curiosity...

php code:

---

$needle = 'needle'; //value to search in the text files
$dir = './dir/'; //dir to folder containing text files

$files = scandir($dir);
$arr_count = count($files);
$i = 0;
$cur_file = current($files);

while ($i<$arr_count){
    $ext = substr($cur_file, strrpos($cur_file,'.') + 1);
    if($ext == 'txt'){
        $line_array = file($dir.$cur_file);
        $line_count = count(file($dir.$cur_file));
        $n = 1;
        $cur_line = current($line_array);
        while ($n <= $line_count){
            if(strpos($cur_line,$needle) !== FALSE){
                $line_quote = str_replace($needle,"<b>".$needle."</b>",$cur_line);
                echo"Found value in $dir"."$cur_file <br /> $n - $line_quote";
                exit;
            }
            $n++;
            $cur_line = next($line_array);
        }
    }
    $i++;
    $cur_file = next($files);
}

Creates an array of the contents of ./dir then progressively checks if each value is a text file, if so, each line of this text file is read into an array, which is then progressively searched for the search value $needle. When $needle is found, it stops searching and the path to the file is echo'd, along with the line number and quote of the line with $needle in bold. Can be easily modified to create a file results.txt with this info in, and to search through all files etc.

php code:

<?php

$dir = "D:/";
$toFind = "xxx";

foreach(new DirectoryIterator($dir) as $file){
    if(!$file->isDir()){
        $ext = trim(strrchr($file, '.'), ".");
        if($ext == "txt"){   
            $fp = fopen($file->getPathname(), 'r');
            while($fp && !feof($fp)){
                $line = stream_get_line($fp, 2048, "\n");
                if(strpos($line, $toFind) !== false){
                    echo $file . "\n";
                }
            }
            fclose($fp);
        }
    }
}




?>
