changing the date of a file on a webserver

I got 10000's html files hosted that where from 2004 to 2006 etc

is there a script or programe i can use to change the 10000's html files date from 2005/2006 to 2008

thanks

i found a lot of file date changers on google but they only work with windows

If you're using *NIX (UNIX/Linux) like I assume, couldn't you write a simple PHP script that just rips through all the files in the directory, opens them and then saves them all, changing the modified time to the day the script was run on?

Here you go, just remember to change the DIR_HERE to the directory the files are in (e.g. /home/user/public_html/filedirectory/):

PHP Code:


		
			
<?php

## Variables

# Directory

$dir = "DIR_HERE";



## Code

if($handle = opendir($dir)) {

 print "<p>Processing files...</p>";

 # Loop through files in dir

 while(false !== ($file = readdir($handle))) {

  # Get file data

  $data = file_get_contents($file);

  # Write data back to file

  $fp = fopen($file, "w");

  fwrite($fp, $data);

  fclose($fp);

  # Give output

  print "<p>Done &quot;".$file."&quot;</p>";

 }

 # Close dir

 closedir($handle);

}

print "<br /><p>Finished</p>"

?>

you can use the system command touch to change the timestamp on a file as well. no need to use all the resources to open/close a file.

Yeah, touch is way more efficient and is designed to do exactly what you want.

thanks for your help
will it change the date on all files?

go to the directory where the files are and run this command (ssh)

Code:

find . -name "*.html" -print0|xargs -0 touch

P.S. the php script above changes all files regardless of extension

As darksoul said, the script I provided will change all files regardless of extension, and is admittedly exhaustive on CPU and I/O resources because it has to keep opening and closing files. You would be better off taking darksoul's advice and doing the following:
